Hey guys, I need some help
This just started, when I give the car gas it will randomly misfire and sometimes it won't. But this is a really stressful prob. I'm no sure where to start. I also know the codes I'm pulling if that helps. Its a 1999 drive train and ecu
Things I've tried:
New plugs
new fuel filter
cleaned the CPS (camshaft position sensor)
P1505
idle air control
solenoid circuit
intermittent falt
(no clue where to start)
P1135
HO2S11
heater circuit low input
(i think my fuel/air gauge spread the signal too thin)
P0420
catalyst system
efficiency low
(no cat, lol)
P0300
Random/multiple cylinder misfire
Someone told me to clean/replace the IAC I'll look at it today.
