I disconnected the cold start injector in the manifold; same thing happens.
It seems to hunt during the sputtering episodes. It would idle ok for a couple seconds, then sputter, then idle ok for a couple seconds, then sputter.....
Vacume never drops below 18.
This started happening all of the sudden. I didn't do anything to the car recently that I could attribute the problem to.
When it runs cold after start up, it runs absolutely fine with out any problem.
I didn't check the timing.....I guess I should do that.
I think the thermostat is stuck open because it takes a looooong time for the temp. needle to come up. When I drove the car (a few months ago), it would take about 15 minutes for the needle to be at normal temp.
