Yes, one possible guess might be a small coolant leak that only leaks when the engine is turned off. That can foul a plug for a little while at start up. But this thread is old enough, by now one would expect the missing coolant would be noticed. -jim

Seems kinda unlikely. No coolant loss noticed, no white smoke at startup. I'm not defending the diagnosis or what was done, but this last fix seems to be working, with a couple of thousand miles on the car since the repair. Over the previous 2 years and 10s of thousands of miles the problem always resurfaced (after each of the several other attempts to fix it) the first time I started the car with temps below 50. Previous attempts to fix the problem included replacing plugs, replacing wiring to the plugs, replacing an/the oxygen sensor, replacing the fuel pump relay, and a couple of other things I don't remember. Best regards to all.

There doesn't seem to be any missing coolant or any smoke out the back. |
