    Sporadic starting issue

    I'm betting on cap,rotor,ignition control module related and when you were in there working on the air cleaner you bumped it.

    Cooling system mess...help me out

    Also an excellent way to test a pcv valve. It can be done with a sheet of writing paper over the oil fill hole with the cap off.

    Smog delete

    My 92 work truck doesn't have smog or AC from the factory. You could try finding an ECU from a W/T model.
