| Ok I have been tuning my car for a while, but I cant seem to get over this one problem. When I start the car and run it for a bit, it runs fine; + and - 5 fuel trims, but when it gets a little hot, the fuel trims get pegged at -22.4 untill i start moving. What can cause this? | |

| Not just his car, but mine too. We made sure the EGR code was set so it wouldnt cycle while siting too. _________________ 1996 with 254k miles, L32 4" FWI -> ported N* -> Ported Gen V w/3.0" Pulley, Stage 3 Phenolic I/C, ZZP FMHE, 1.84 RR, Headers and 3" pipe to mufflers, F-body brakes, and lowered on Eibachs. -RIP AMG C400 White on black.
