As many of you already know I recently bought a 2004 coupe. This is my daily driver now. The car runs very well, but let's face it, it's for all practical purposes it's 10 years old. Does it make sense to do the RCM fix and PCM fixes as a preventive maintenance? Any other potential fixes to conciser?

 

I've considered changing my CPS but they are still working so why bother? A new CPS can fail just as easy as an old one. The RCM on the other hand is a preventative maintenance type thingy. You fix it and it should perform as expected. Same thing with the Sticky Ignition Key fix. Preventative maintenance.
Do it and yer covered. (I've yet to do the Sticky Key fix and I know it's gonna bite me in the @ss one day! Howard offered to help. Waiting for nicer weather)

 

Thanks TJ. Being a daily driver, you think it's wise to just have the PCM sitting on the shelf, or are easily available at local European auto parts stores?

 

Offer still stands TJ. Just let me know. FP... Pulling the RCM to check the solder points is easy. Use a high power magnifier. I resoldered the suspicious ones myself. TJ has RCMs to trade off already soldered. Maybe he would send you one to install, and you send your old one back to him. The sticky key fix is more labor intensive, but if I can do it, anybody can. Just follow the thread for repair. Don't wait till the key won't turn. I removed the ignition lock and popped out the springy thing and little rod, put it back together, and reinstalled. That was 2 years ago, and smooth as silk since then. Figure on taking about 2 hours to do it. You might want to consider using Gary's heated garage. If you plan on getting a CPS to have a spare, MAKE SURE its not a cheap China one, get a good one. I don't remember the brand, but I'm sure someone will chime in. Where's 180 when we need him. LOL Have fun .........

 

The CPS should be a Bosch.

As far as other preventatuve maintenance, beyon the CPS, the RCM soldering and the sticky ignition, you might think about the battery and the tranny connector leak as the most likely things that can happend that will be road worthy issues. As you know, generally these care are pretty reliable other than a few of these common problems.

 

Howard and TJ, let me know if you can send me an RCM ahead, and I'll send you mine. I have no issues with mine. Just trying to prevent an outage. Send me a PM on how much it is.

Thanks

 

I carry a Bosch cps in the trunk. Resolderd my RCM two years ago when I did the key fix.

Those three items are probably most important FP.

 

FP .... TJ is the one to contact (tighed1). He's the one that will exchange with you, generally no charge, except to reimburse HIS shipping. Just PM him.

 

What PCM fix are you referring to? Curious...

 

I am thinking RCM...but might be wrong...

 

I'm guessing PCM (powertrain control module)? is actually TCM (transmission control module).

 

I guessing mine will all go at once since I haven't had any problems yet. I did put a CPS in the roadster awhile back, and a ATS about the same time. Coupe hasn't had anything done yet.

 

James, my bad. i meant to say CPS. I must have been thinking about a previous unrelated term I was working with. That's what happens when you try to multitask when you're old...

 

I agree why change something that works, I did the Sticky Iggy thing though.

I learned that lesson young when my GranPa gave me a nice watch and I wanted to see what made it tick, I never found out and it never ticked again.

Remember the Crossfire motto, 'Go Bosch or walk home'.

 

OK, questions for our RCM experts; I had no issues with my RCM, but decided to replace it with one from DJ, as a proactive measure to avoid a potential outage down the road. He sent me his RCM, but after I installed it, I got an "check engine" light. The code is P0410. I put mine back, and the light went away. Now I have the light on again with my original RCM. Any thoughts?

 

P0410 as you know is the air injection code, maybe the contacts on the relay are burnt or there is a poor connection of the ground wire.
Do you hear the air pump working at the start up of the engine? Does the pump run all the time? Does the pump ever run?

 

Probably that pesky relay in the RCM.
The RCM I sent ya (FP) came from my coupe that didn't have any fault light indications.
Once I get another RCM I'll try the relay swap and see what happens. Meanwhile I'm swapping the RCM from my roadster between the to cars so I can drive them.
Anyone have old RCMs laying around???

 

You know, maybe I never paid attention, but I don't think I ever heard a pump running on this one or my previous Crossfire. I do feel air coming out the box where the RCM sits. Is that what you're referring to?

 

No, he is talking about the air pump top front on the engine that sounds like a jet engine when it cranks off.
It should run for about 45 seconds when you first start a cold engine.
It's purpose is to warm up the O2 sensors quickly.

 

So, if I'm getting the P0410 code on both RCMs now, do you think I have a bad pump? Is it hard to replace the pump if that's what's wrong now? I didn't have any issues with my RCM or pump before I replaces my RCM with DJ's. I disconnected the battery per instructions prior to swapping them. Could the swap have caused the pump to fail?
