Hey folks, quick question,


I had a code 35 Canister Purge Valve Solenoid pop up the other night and sure enough I had a really rough idle, misfires, and stalling the whole 9 yards. When I put a meter to the solenoid I got no reading at all just OL on my meter.

Flash forward, I just finished swapping out the solenoid for a working one, it showed about 42 ohms at a little over 70 degrees.

The engine was running smoothly for few moments, but then it seems like the mixture got enriched I could smell raw fuel, and the idle seemed low and rough.

I'm in the process of resetting the computer to see if that will readjust the mixture.

My question is this, can unplugging the canister purge valve solenoid cause your mixture to go out of balance? it was unplugged for about a day.

What is possible is that fuel vapors were stored in the charcoal canister and since they weren't being drawn into the engine that may be what you're smelling.

Quick update. After leaving the computer to reset the 35 code disappeared and was replaced with a Code 15. I'll be trouble shooting the injector tomorrow.

Turns out it was a bad injector. I swapped with a working one from my donor engine. No more misfires no more related codes.

I still have the issue where my RPMs drop really low and then climb back up after a few seconds.

When does the rpm fluctuation you describe occur and does it happen frequently?

Did you ever figure out what the idle issue was? I'm having the same problem. I have a whole new intake manifold to swap on with all new sensors and injectors and what not that are on it. I have code 35 flashing as well and my car idles rough. I think it's an injector as well.

Have you checked to verify the canister purge valve and the associated wiring is good?

It's always a good idea to make the ECU happy so if it thinks there is a bad canister purge valve I'd suggest investigating/replacing it even if you don't think that is the problem.

What is a code 15?

Injector #2

What I did was I cut the ends of the hoses for a more snug fit and it worked great. My code was gone after the first ecu reset.
