Hi everybody. I bought my first fox a couple weeks ago. 90 lx 5.0 hatch auto. The car's only mod was an x303 cam. (YES I KNOW) I didn't put the stupid thing in, lol! Here are my problems:
Right now I am pulling codes 41 and 91. I have been keeping an eye on the plugs and they are now getting white. The car lacks power big time and fuel mileage is between 14 and 16 mpg. When cold the car will not idle unless I feather it. Sometimes even when warm at a stop it will stall out on me. However it usually idles steady at around 1100 once it's warm.
So far I have replaced the coil, cap, rotor, plugs and wires, fuel filter, removed air silencer and dropped a K&N in. I Put the timing @ 12* and I have been running 93 in it. I have cleaned the Iac valve and egr valve. (BOTH were hideous!) And replaced the faulty tps. Tonight I unplugged the FPR vacuum and tripped the fuel pump into running, no fuel leaked out of the FPR. I have not yet gotten a fuel pressure guage so I can't say what the fuel pressure is exactly.
WHERE should I go next?
TFI? Leaking injectors?
I need your help!!
