Sounds like your fuel pressure regulator is possibly going bad. Also check your oil. Does it smell like gas? If so possibly an injector sticking open letting the fuel pressure off the fuel rail.

I would try a can of sea foam to a full tank of gas. This should free it up.

Yeh, set, I ectioly have something new and better than sea foam., will try it now. And I just put it back 2gether after replacing a starter motor on it, what a horrible design, but anyway wen I had the headers out, and was checking the injector seal I do remember seeing in the 3 clndr a lifter was up, being totally bag ed wi the starter reasembly, I didn't really think clearly, I thou at 1 St that it was sticky and got stuck, but then 4 som stupid reason I thout that it just stopped in the middle of the circle that's why it open, but boy I was wrong & stupid, lolz, Hey thanks 4 Yr help anyway and is there a way of checking the pressure regulator, in case flushing won't help???

When you say start issues do you mean it turns over really slow in the morning or after a few hours? Or do you mean turns over like normal but takes more turns to start the car in the mornings?
