Peter_M Member 31 Member For: 14y 1m 23d Posted 16/12/13 07:25 AM Share Posted 16/12/13 07:25 AM Hi All,My 03 4 spd auto ba xr6t is having an issue on startup. When started (generally on cold start) the revs go high which I assume is natural for a tuned xr6t but then stay high for like 15-20 seconds sometimes more, and if I go to put it into any other gear, the engine light comes on and the car will auto stall.It has a wog cooler, upgraded valve springs, 42lb deka injectors, rebuilt auto, cold air intake and tuned to 280rwkw.The following codes have come up on a test:P0171 - System too leanP0238 - Lack of HO2s - 11 Switches indicates lean (B1, S1)P2105 - Throttle actuator control system - forced engine shutdown (assuming when I try to put into gear when revs are so high at startup)P2110 - Throtle actuator control system - forced limited RPM.I have also noticed under WOT I feel the boost having gaps, I can even hear the induction gaps from the CAI...Can anyone give me their 2 cents as I am totally lost at the moment.Absolutely any suggestions would be greatly appreciated.Cheers, Link to comment https://www.fordxr6turbo.com/forum/topic/87073-high-revs-on-cold-start-revs-stay-high-for-15-20-seconds-then-slowly/ Share on other sites More sharing options...

I changed this and the problem still exists, but not as bad as before. My symptoms include the car running really rough, like it is running on 3 cylinders, and I immediately switch it off and back on again and the problem disappears.
