You may have an injector problem. I had all kinds of wierd problems with my afr's. My car would go lean whenever it felt like it. Even when I would raise the fuel pressure. It would go lean at idle and sometimes when just cruising. I was running venom 660 cc injectors at the time. My problems made no sense. And sometimes my afr would go very rich at times without adjusting anything. I switched to dsm 450's and all my a/f ratio problems went away. Good luck.

Ya the only problem is he's pushing 550whp and 10sec timeslips. 450cc DSMs won't cut it!!!

im using 1000cc precision injectors.

btw, I checked the fuel pump and it put out plenty of fuel. I took it out of the tank and test it. No problem there, good pressure and volume.

next thing to check is the injectors. im gona see if I can borow some 1000cc rc injectors from a buddy of mine, and see if that fixes the problem.

wish me luck. im not letting this problem kick my ass, im gona find the problem. there's nothing elese im gona do to the car, untill I fix this problem.

btw, thank you guys for helping. :-* ;D
