My '90 stopped turning over at the key switch. It starts just fine when I jump the solenoid with a screwdriver.Bouncy tach still for 15 to 20 seconds. I installed new IAC already. It will set and idle ok, after 4 minutes or so, I see slow drip out the tailpipes. Condension ?? Anyway, when I put it reverse to back out of the driveway, it has a tendency to stall. Any ideas on that guys? All thoughts appreciated. I got new plugs,(not installed yet) , AWSF 34PP. What should they be gapped at? I think I set them at .56. I want the gap to be right before I put them in.
