Re: Trouble codes
Random thoughts, but I'm no mechanic….
Put a stethoscope on each injector to see if they're firing correctly.
Pull each plug and ground it and then watch it spark. How do the plugs look?
Fuel rail clogged? Bad pressure regulator on the rail?
Intake manifold leak?
It's been my experience that one bad injector will make your trims on that side look bad…but not misfire multiple cylinders.
Good luck with what is probably very frustrating!
Wil
also, have you run an ohmmeter on your harness to confirm wiring?
