Default LPG Conversion

Hi everyone,
Still kind of new here so apologies if I have posted this in the wrong section,
I just wanted to let you all know I have my crossfire being installed with an LPG converter today and so far it looks great. Petrol here is £1.46 while LPG is only £0.68 so it is a big difference and I do 120 miles a day It will be finished by tomorrow and so will post some pix and feedback when it is done. But surprisingly enough there is still loads of space in the boot despite it having a 70l tank in there

I have run my SRT on LPG for over a year and travelling in excess of 500 miles a week it has certainly saved me £££s. I have a 55 LTR tank and with the roof down I have no space in the boot. But as I have always told the sceptics... I didnt buy it for the luggage space. Conversion cost me £1500 and the conversion garage is a short drive from where I work along with a LPG supplier charging now 74 Per Litre. My car travels 230 miles on a full tank which costs about £30. That equates to £10 per 70 miles. Now compare that to the cost of Petrol and you will see the savings. Performance??? none because I burn it when I feel like it and dont worry how much it costs with metal to floor.
Happy motoring all you Crossfirers and keep up the threads.

Hi Steve! Good to hear from you buddy? How's it going? Where did u get the car converter? Do u have the cylinder or the tordial donut shape tank? I have the tordial tank but they had to cut the trim to fit it in which isnt good because it looks tacky now. So glad there's someone esle out there with an lpg conversion. I need your advise please I have had nothing but problems since I got the lpg conversion in my crossfire I have no idea if it is just a coincidence that the problems have started since it was installed or if they damaged it as they damaged a few things while installing it because their workmanship is awful! I have no power in my crossfire all since it was installed. It keeps jerking and hitting flat spots especially when halting to a stop and then trying to move again. It almost hesitates to move. Before I would put my foot down barely a cm and the car was so responsive. It also either revs too low or too high. The problems are both on lpg and petrol, and they claim they didn’t touch my petrol side of things BUT they blew a fuse in the system when drilling holes under the car to install the pipe work. I get a good 250 miles to a tank but that is no good if I have the basic crossfire 3.2 (not the srt) and the tank is 70l. It feels like i am driving a 1 litre fiesta. Maybe i should see ur installers? Hope to hear from you. Thanks, Alex J

Hi Alex... your not gonna believe this but I too had exactly the same problems after I had the conversion. The LPG fitter was at his wits ends trying to fix the problem. Before I tell you what the final outcome was let me let me tell you what I did. I joined the AA extra repair. That gave me upto £2000 of repairs a year for only an extra £50 on top of the normal relay/roadside repair. Now let me tell you what happened after that. I got a mechanic who just happened to be a friend of the LPG fitter and got him to have a look at it. This guy who I shall name Tony used to work for the AA. Because my management light came on I called the AA and they could not fix it at side of road but followed me to Tony's garage...following me so far? Tony, who just happened to work for AA a few years ago diagnosed the problem as coils which is fitted to each cylinder. It turned out 3 had gone. He replaced each one and sent AA the total bill who paid it and hey presto... the old beast is working fine again. My advice???? Get a diagnostic check, if it turns out to be your coils also, join the AA. Dont tell em I told you. Let me know how you get on. Steve B

Forgot to ask you your e-mail so I can give you the name of LPG fitter who will be only too aware of the problem you and I experienced.

You just have to excuse us over here, we aren't paying what you pay for petrol right now, and hope we never do. I have had some experience with farm machinery on LP as we call it, but only a few trucks. It seems to do fine, with some power loss, but not bad. Now, the farm boys racing their 4-wheel drive deisel turbo charged trucks will inject LP into the turbo and develop huge HP.... LP is around to stay, but just isn't used a lot in autos over here. Mostly industrial equipment.

I work in the heavy equipment world as a repair technician. They are doing some pretty cool things with LPG now that is really bringing the power back up to regular gas engine specs. Direct propane injection has been developed for quite a few forklifts and they perform quite well compared to a gas powered unit. The old carb style mixer body systems that convert the liquid to a vapor to be burned are the ones that are notorious for being wimpy and quite sensitive to temperature changes.
Its definitely here to stay, but not as cost effective to convert vehicles to over on this side of the pond.

STEVE!!! So glad u were in the same boat as me! Least u have it sorted. I have taken the car to various places but they cant diagnose the problem as their computers dont work with the cars ecu and so have been told to see chrysler. But the chrysler by mine charge £120 for a diagnostic and £102 per hour labour exclusing tax and supplies! It's robbery! I have the AA warranty that came with the car when purchased and the coils are covered but i have to get someone to diagnose it before the AA will pay out for it, but I dont trust the chrysler by mine (they havent been chrysler for long) and they just want money money money. Any ideas?? It feels like the coils, how many coils are there in total? THinking I should replace the lot? But i hear it is a waste of money as it is best to sort the problem out and not the symptoms and so need to learn what is causing the coil problems first. I will p.m in a sec buddy with my details. Is your car working fine now? I had such a nightmare with my lpg, the tank keeps making noises so have had the credit card company deal with the people! It honestly looks like a 6 year old did the work and now having other companies just repair the damage these cowboys did!

@ oledoc2u and MoparFreak69: I have to admit, I wish i left my crossfire alone as it has had nothing but problems since. My gf asked me why get a car that is high on fuel usuage and spoil it with lpg, but as said to the other guys, I just like the car's body and wouldnt care if it had a small engine, just want an engine that works haha When over in the states I used my friends chevy pick up which was converted with lpg and it was still a rocket ship but as you said thecost of petrol/gasoline is not high enough to justify the lpg installation unless the lpg installtion was very cheap. But still, wouldnt ever go back on my crossfire and was the best buy ever!

Alex, you should be able to do a continuity check on the secondary wiring inside the coils. Take a VOM and ohm out the two spark plug wire terminals on each coil. I think these coils (being the secondary) should read continuity between the terminals. I had a 6 cyl GM 3.8L that used the waste gate method of burning excess fuel on the exhaust stroke so each cylinder fired twice on each crank rotation (once to ignite and once during exhaust). Anyway, the coils are just a step-up transformer and you should be able to check the high voltage side in each coil. Note this is done with the car OFF, and the coil wires removed from that coil your testing. As you do each ciol, replace the wires then go to the next one. All the coils should read close to each other. If you get one (or more) with no reading, that secondary is 'open'. Your only testing one coil at a time and only those two spark plug wire outputs. That 3.8L I had had two oif three coils open. It ran great but when a heavy load (hard accell and A/C) it would cut out like someone was turning off the iggy.

Hey GraphiteGhost,
I finally gave in and took my car to the chrysler dealership for them to look at the car. Well it turns out after everything, the fault is all down to the LPG installation itself. Turns out the lpg installers hve installed the system incorrectly nd hve not installed the correct systme for the car with such an engine size. The chrysler people were really friendly and I got a key ringb and box of candy fter everything. I know the cost of diagnostic was a bit steep but you get wht you pay for and they had it for severl hours and wrote me letter to issue to the credit card people and lpg installers proving the problems re result of the dodgey lpg installation and it needs to be fixed. I will be getting it either removed or repaired, however whatever happens, the installers will foot the bill as it is them in the wrong. I feel so sorry for my crossfire, poor girl haha. It is either a lesson learnt not to install lpg or just use a better instller

Unhappy Re: LPG Conversion

Hi Guys,
I'm reading all of this with interest as I have been seriously considering a conversion. I love my crossfire, but I'm changing jobs and need to get more miles to the gallon. It's a tough one, but I just like to get in my crossfire and drive, then have it serviced every year with no hassle. I'm thinking the conversion might be a bit too complicated. Can anyone give me any assurances before I put my car on ebay!

Hi mate,
There are many people who hve positive experiences with lpg installs and many like me who has hd bad ones. To go with this there are many pros and cons. With a great install I am sure LPG is worth it however lesson to learn as I have done, you get what you pay for, if it is too good to be true then it is and if it is very cheap to install then it could be because the installers are rubbish.

My advice is research on lpg, see if u are happy with the boot space loss, having to wait ages for the lpg tank to fill at the station etc etc and if you want it, find a place that you have heard off and have been recommended by. My chrysler/land rover garage recommended me to this new lpg place where I am getting a report and repairs of this shuddy lpg install I have. Chrysler and land rover wouldnt recommend them if they were bad as it could effect their reputation as well. Just an idea, perhaps ask around. I have been told now to always use a place that is either approved by autogs/uklpga. Hope this helps

Hi Supermanalex,
Well that's made my mind up. There is no way I could cope with that. I panicked when I had a puncture!!! Much as I love the power, I think I'm going to have to give in to a girly mini or beetle or something. I hope you get to the bottom of your problems soon and get it sorted out - it doesn't seem right that the garage has got away with such a dodgy conversion.
