Bam Posted July 4, 2005 Report Share Posted July 4, 2005 Ok, I've got a 2001 GTP w/ 53k on the clock. Was stock until about a month ago and I made a few adjustments. Maybe I fucked something up, maybe its just my luck, not sure. Anyways, It ONLY seems to stall out or lose power when its HOT out, and ONLY in the city, freeway cruising is fine. Also, when having the AC on it's more frequent. The car will always start right back up and drive ok, sometimes when I'm coming off a light and I give it tiny gas it goes, stumbles, goes, stumbles, etc etc. Then if I'm driving at like 35 it might just stall out. What's going on? A few ideas people threw my way are...serp belt slipping, alternator going, fuel pump/fuel pressure regulator, and a vaccum leak. Someone help me please, I need my car to be reliable! Thanks Matt Quote Link to comment Share on other sites More sharing options...

Nate1647545505 Posted July 4, 2005 Report Share Posted July 4, 2005 Buck hes got a 3.4 and an intake, and the ubend removed. Uh, it did throw codes on the fuel pump relay so maybe thats a start? Have you replaced that resistor yet Matt? Quote Link to comment Share on other sites More sharing options...
99ta Posted July 5, 2005 Report Share Posted July 5, 2005 Mine stalled out like that and it was the resistor, easy fix for $15. I would try that first. Quote Link to comment Share on other sites More sharing options...
Bam Posted July 5, 2005 Author Report Share Posted July 5, 2005 It throws a code for the fuel pump, but as of saturday once I cleared it and ran the car for a bit then logged it, the code didn't come back. Maybe it's back now, I haven't checked. Also, maybe my car does have a resistor but everyone is telling me that 01's and newer don't. I went to the dealer and they said no parts relating to that for my car, only 97-00. Also, I talked w/ about 10 guys on saturday and they all said the same thing and one guy checked something in my passenger fender and said he couldn't find it. So maybe I do have it, but I don't know what it looks like and I can't find it where I was told to look. You guys want to meet up and check for it?

99ta Posted July 5, 2005 Report Share Posted July 5, 2005 That might be true...I am not sure mine is a 00. Go to clubgp.com and search for fuel resistor. That where I got all my info. Good luck. Quote Link to comment Share on other sites More sharing options...
Bam Posted July 5, 2005 Author Report Share Posted July 5, 2005 Checked out clubgp.com and read up on the resistor. Checked under my hood and compared them to people pics showing how to bypass the resistor, and I don't even have the relay in my fuse box under the hood. So must be something else ?????

nachius Posted July 6, 2005 Report Share Posted July 6, 2005 I had a similar problem on my 97 it was the fuel filter, but you have a lot less miles, so I'm guessing it's something fuel related. I'd get it warm and test fuel pressure and go from there. Quote Link to comment Share on other sites More sharing options...
Guest GMoney Posted July 13, 2005 Report Share Posted July 13, 2005 May want to swap out the map sensor it will just stall with no codes it gives an incorrect intake pressure reading if its cheap from AZ sometimes there only 15 bucks Quote Link to comment Share on other sites More sharing options...
