In the Spirit of Easter... Resurrect My 240!! She needs help! Advice?
In the Spirit of Easter... Resurrect My 240!! She wont idle, and seems to be running lean under boost.
First a little background info:
95 Turbo KA 10psi
upgraded fuel system (pump, injectors, ect..)
Apexi S-AFCII for fuel control
greddy boost controler
2 months ago my brother was driving my car charge pipe popped off so it flooded the system with fuel. Has kind of run like crap ever since.
2 weeks ago, my brother called me, and told me there was oil coming out of my BOV. Turns out it was coming from my PCV valve. I pulled off all the charge piping filter, and MAF sensor, boost control lines and cleaned out all the oil, and cleaned the k&N filter, then cleaned the maf sensor with maf spray cleaner. Reinstalled with an oil catchcan and breather.
2 days ago, So then the car would not want to idle, so i'd blip the throttle to keep it alive then after about 15 seconds it would be fine. Now it was running lean according to an autometer narrow band, which means its running "super lean" (the way i understand it is the narrow band reads something like 14.5-14.8 or something like that, correct me if i'm wrong), so knowing that the motor is running way too lean under boost.
2 mins ago, now the car wont hold an idle for nothing, it will start, but i need to crack the throttle a little immediately to keep it alive... I have no idea whats going one here, but i am about to give up lol
Any possible ideas? could the oxygen sensors have fouled out from when the charge piping blew off and ran all that raw fuel through? now that the maf sensor is clean could it be sensing more air so its adding too much fuel at idle?? (assuming that the sensor was not 100 percent clean at original time of tuning...) What do you guys and gals think. I am stumped and tired, a fresh set of eyes would help!
