Ok guys , i need to know what you guys know about fuel trims. My car is running way lean and i cant figure it out . All my fuel trims ( no matter if at idle or WOT ) are well over 100%. I have a walbro pump and the rest is stock. ALthough i do have a new fuel filter. I have switched the injectors twice now and that did nothing. The O2-R reading fluctuates between .3 to .9 all the time.
I just need some of your ideas since im not very educated on the hole tuning part yet. So just gimme some info on things to check. Oh, and ive also changed the FPR a few times also, my brother has my aeromotive on his car but i will get it back very soon. thanks -------------------- "One of the most Crazy and Undecisive Members in central Illinois"

Natedogg and NCGalant will be your best bet for explaining fuel trims from my experience.
