It could very well be an injector, you never know, but the car runs perfect and gets no drop in gas mileage, and idles smooth,a nd no fuel can be smelled, which would be a sign of a leaking injector or something.
I think it has either something to do with startup enrichment, for warm starts. Cold starting is better, but warm starting is tough, and seems to be getting tougher.
At first it appeared to have worked with cleaner, but I still have no improvement now after a couple of days of it being better. Its weird, its not a consistant thing.
This leads me to thinkt he ovp might be the culprit as this sounds like one of the symptoms of the ovp from other reading I ahev done.
I'm going to talk to my mech about it and see what he says.
