This is starting to bug me, and I'm sure it's not good for the car either.
For the last few weeks my GN has consistently backfired when starting up in the morning. 4 out of 5 times it'll start right up afterwards and run fine, 1/5 it'll run like it's on 5 cyls for a minute till it clears up. FWIW, it seemed to start when the temp dropped into the 50s from the 70s.
I've dug through the archives with little success. I did find a recommendation to check the CPS, so I reset the clearance on that to .025, but no joy (stopped the ticking though! )
From what I've read, either the coolant temp sensor is sending a temp that's way off, I have a sticky valve, a leaking injector, or some combination of the above.
I'll throw T-link on it tomorrow morning to check the temp sensor, try some "valve unstick" additive, but if that doesn't work, what's next? I had the injectors cleaned a year ago, so they SHOULD be OK.
Anything else I should check?
