Engine still misfiring after changing to OEM Plugs and Coils
Engine still misfiring after changing to OEM Plugs and Coils
Like 3 days ago i finally changed NGK plugs and Hitachi Coils from RockAuto and it didn’t bring up an engine light but somehow this morning the engine light flashed when cold and somehow started funny so I took the code out and runs normal, so idk what’s happening is it the injectors, gasket idk because it’s really getting annoying
(also someone was using my car when it happened so idk what the code was but the engine light happened)

I already posted this for you in your last thread here it is again.
It’s possible an injector has failed, have you tested them? The injectors should all read about 10ohms, also the injector clips should have 7.3 volts at key on engine off. If your readings are outside this range you have a failure, do not swap injectors around to test if this is the case you will ruin more than one.
If you find a bad injector which I suspect you will, your ecu is likely also no good and will need replacement and re programming along with the injector replacement. Unless you can find someone to solder in some new mosfets for you.
here is a link where I discussed it further.

cleaning them will do nothing if they do not read correctly with an ohm meter. If they don’t have the correct resistance the circuit has failed internally.
So no if they test bad they must be replaced.
