Not really a serious issue but I've noticed today, when driving to Orlando (and sometimes on the way to work), that when I'm cruising at about 80 the car sometimes lurches without me touching the gas. I didn't know what it was but I figured out that the supercharger wasn't being engaged. After it happened I tried to gun it and it was puttering along. Every now and then I'd try it again and the supercharger would engage but then slip off again.

So is this an IC pump issue or Supercharger issue itself? I have a warranty until I reach 70K miles, it's just a matter of where the problem lies.

 

I too have the lurch, occurs between 70 and 80.
Not sure what to do about it 'tho.

 

Mine does it to. It's almost like a extra boost of power from somewhere. I wonder if it's from shifting into overdrive.

 

Sounds like the very beginning symptoms of the IC pump going out. It may take a week or a year for it to die completly.

 

when my ic pump failed i notices a loss of power it would come and go
but around 80 it would not go any faster

 

Yup. You hit the nail on the head there.

 

Got to the dealer to have them look at it last week and htey said it was the IAT sensor throwing a code . Better than the "Injector Service" some bitchy woman suggested to me when I got there. I laughed inside. Anyway, they reflashed the ECU to reset it and it happened again.

So, today I bring it in and they FINALLY looked at the pump, ran a diagnostic and it came up as being faulty so I'm getting it replaced on Friday. I'm going to read over my service contract and see if I can change it out with a Johnson pump w/o voiding my warranty.

 

Your old car is running well, My son took it today on its first trip to Fort Lauderdale.........and he loves the car

 

Mine lurches occasionally, but usually if I'm puttering right at the 2300-2500 rpm mark. I believe its just the sc engaging at its required rpm. No problems when driving aggressively or cruising at 80 on the freeway. I know the pump is going to go some day, so I'm prepared.

 

Mine is doing the same thing. Runs like crazy around town, but isn't too great on the highway. I get the surge thing too. I guess my Tax Rebate check is buying a Johnson Pump and Spacers...

 

LOL........See Gator, your old XF doesn't miss you. It found a good home.

And by the way, hopefully they will change the temperature sensor when they change the IC pump.

 

I already know if it happens again I'm just going to get the new HE and pump and be done with it, maybe the Spacers as well cause it does get pretty darn hot here in FL

Randy, from what they told me it was only going to be the pump

 

he went to look at a SRT6 for 16,990.......

 

Sandy you should have called me I would have checked it out for you. But, then again your son would have still had to do it himself. Besides it gave him a good excuse to take a nice cruise to FLL.

 

His dad owns southern comfort AC so he went to visit.........

 

I would like to know about this also mine doing the same thing only got 6700mi. on it?????

 

Just go to the dealer and have them check on it. They will most likely pull up some code that has to do with the IAT sensor. Tell them that's not the problem. The reason why the sensor is throwing a code is that the coolant isn't running due to the pump and overheated.

Not sure what the tech did with mine but on the second visit they declared it was the pump. What you could do as well is to take it in and if they give you any crap have them call my dealer since they're working on this exact issue in my car and maybe the 2 Xfire techs can hash it out.

If they do end up calling just say you were referred by the guy with the Graphite Roadster that was in recently with a pump failure.

Hope this helps

 

Don't no if I sent you a thank you for the info on the ic pump or not but here it comes THANK YOU
