Spark plugs were wet when last removed. I'm guessing could be fuel or oil fouling... haven't got so much experience to be able to tell... Also concerned about the gas smell after the engine starts (I think more pronounced while the engine is cold), so I'd like to think my problem is fuel-related. Another thought is that I put synthetic oil (Mobil 1 10W30 High Mileage) at the last oil change, and as far as I can tell it had some cheap stuff in it before (from PO) which hasn't been changed for a while. This could be a far shot, but maybe the slicker synthetic oil in the engine that got used to dino, started finding its way into combustion chambers and creating this sort of trouble. If that would the case I sure hope it's reversible (the car ran for about 1K miles with Mobil 1).
The car still runs pretty nice all these problems notwithstanding, so I'm hopeful things are going to sort out with not too much work.
