running lean WTF on stock z6
 

i dont ------ get it, i have a little bullshit short ram intake (pipe and a sock), i changed the fpr, and all cylinders are running lean and the temp guage goes to the middle. the spark plugs are white as bone, and my last ones started getting purplish dots on them (from overheating i think). i dont get why the ---- its doing this. the engine is completely stock besides a flywheel/clutch and my gay intake

someone help me out here, can a bullshit intake make you run lean?

Re:running lean WTF on stock z6
 

did you drop the fuel pressure?
maybe thats why? ::)

also how do you know its running lean? did you check with a wideband? and was it calibrated

also metal specs on your spark plugs is a sign of detonation; thats molten aluminum cooling on the inulsator

Have you tried a tune up. If the car was abused and ran w/ crap gas injectors do get dirty which can casue a lean condition. I would get some fuel injector cleaner and a tune up

Do the basic maintanance...but I bet it could be the fpr...maybe you set it to low...you need a fuel pressure gauge to set it up right.
He's running lean, cause his spark plugs are white...he has detonation..thus the aluminum bubbles on his plugs...and if his car is getting hotter then before ... he is getting higher EGT's
Check the FPR first...is ti adjustable?

maybe the fuel pump is going out or the fuel filter is clogged

Re:running lean WTF on stock z6
 

i have a stock FPR, im gonna put in new injectors from my other car, and im gonna try and change the feul filter, and i think i have a spark feul pump, and if that doesnt work, well i dont know wtf is going on

Re:running lean WTF on stock z6
 

Trust me you have a clog in your fuel system somewhere no biggie do the basic tune change fuel filter etc and the car will be fine

Re:running lean WTF on stock z6
 

i changed the feul filter, checked the feul pump and the plugs are still bone white
