Of problems and what has happened up until today. 18th. Two week's ago car ran great. Upon starting the engine one morning there was a backfire thru the throttle body. And then a loud hissing noise like air leaking from somewhere. Too many codes upon scan to list. Repairs done.
Intake manifold and runner control valve replacement. New throttle body.
Replaced all coils. New plugs. Stopped the hissing noise but still runs ruff.
Now the lightning bolt display is flashing and will not go away. Reset throttle body multiple times. Yesterday I replaced the PCM/ECM.
Things smoothed out a little bit. Today I unplugged the runner control valve to do a volt test. Reading was 0.0.8 forgot to plug it back in started engine and to my surprise it runs a lot smoother. I also damaged the MAS or MAF sensor whichever one it is. At the bottom of the intake manifold. I unplugged it as well and now I can actually drive the car short distance.
The lightning bolt display still blinks and will not go away. As crazy as this sounds. It's actually running better but needs these sensors replaced and plugged back in. Can anyone please shed some light on my situation?
Thanks. JC
