2000 X bad idle, bad mpg, did everything!
So I hate doing this but I am at a loss with this. I have searched and searched and done all the recommended stuff but still not change. I am not even remotely new to building and modding cars so the fact that this is stumping me is really pissing me off.
-has just over 100K miles.
-no check engine codes.
-Idle’s like crap will die occasionally at idle.
-Drives and accelerates fine.
-Gets about 120-140 miles per 16 gallons of gas.
-mods are CAI, and muffler
-I have replaced: plugs (ngk), wires(oem nissan), distributer(a1Cardon), fuel pump(bosch), fuel filter(bosch), cleaned MAF, radiator(dayco) and timing belt with all associated bits.
Still idles like crap and still gets poor mpg. Help!!!!! My Audi was easier to fix then this thing is.
