My car run too rich ( it is running like that for a while and now too long)
i changed the O2 sensor, it help a bit but now its still bad.
With a scan i discovered that i run too rich, as soon as i touch the throttle my spark drop under 10.
MAF was good, the O2 is good, fuel pressure is good.
I heard it can be the crankshaft positionning sensor so i decided to go to the dealer to order that sensor, but i ask to a mechanic what are the symptom of a bad crankshaft sensor.
With the symptom my car have, he tell me thats my intake...?!??
He told me that if it was the sensor, i should here a noise from it. And he saw a guy with a GTP running an intake and having that kind of problem and once he get it back to original air box the problem was gone..
but i runned the Fender well intake like 3month before it begin to do that, and begun like 3 week after the install of my hi-flow cat.
This thing begin to be really annoying, should i change the crankshaft sensor or not?
Practicaly everyone here use CAI, or FWI without any issue, telling me thats my sensor.
thank you for any help, info or advices.
