GEAR M UP Posted January 12, 2004 Report Share Posted January 12, 2004 Do any of you guys notice a lag or pause until your truck warms up. I have noticed that my truck lags or almost stalls when I get going in the morning, low speed under 10 mph. It goes away after I get going...

BenKey Posted January 12, 2004 Report Share Posted January 12, 2004 I get the same thing. Link to comment Share on other sites More sharing options...
slimsoftball Posted January 12, 2004 Report Share Posted January 12, 2004 I had the same problem. That is until I got it tuned. Of course I always start it and let it get up to temp before I leave in the morning. Been doing that every since I put in the new springs. Link to comment Share on other sites More sharing options...

dcairns Posted January 12, 2004 Report Share Posted January 12, 2004 I just start it up and go, driving easy till it warms up. But I do notice a similar thing, a slight stumble on accleration. It never seems like it is going to stall. Link to comment Share on other sites More sharing options...
blownchevy Posted January 12, 2004 Report Share Posted January 12, 2004 This is usually a sign of a fuel pressure regulator problem. I would check the install of the regulator, this needs to be lubed up ALOT before it is installed in the feed block. Link to comment Share on other sites More sharing options...
blownchevy Posted January 12, 2004 Report Share Posted January 12, 2004 Another Idea! I just thought about it a little. We had an H2 in the shop that had the same problem, we checked the FPR and it was fine. After further research we discoverd that the cold start programming was off in the tune. You should contact either the shop that installed the kit, or MagnaCharger direct and they can help you. If you do not get anywhere with that, please feel free to call us @ 818-340-1714 and I will do my best to help you. There should not be a charge for this adjustment other than shipping (we dont charge shipping). Let me know if there is anything I can do for you.
