I was at the track on monday and before i could even run it the car started to die... It will start back up and idle like it has a bigger cam than whats in it.. it is showing code 44 which is - Bank 1 (left) o2 lean.. i cant figure out how to fix this problem.. I'm tired of this damn car throwing stupid problems my way.. last week was the ignition moduel, than the thermastat, and now this.. can any one help... Oh and the o2's are brand new. less then 1,000 miles on them...

 

oh and just checked the codes again and now its showing 55.... which is some thing about fuel system monitor lean.... it acts like the damn walbro is going bad... please help guys...

 

Check your fuel pressure. Are all injectors plugged in and working?

 

all the injectors are pluged in and appear to be working... i dont have a pressure guage to check it but i've talked to a couple guys and they all think it's the fuel pressure regulator..

 

i would check fuel pressure before anything else
