If you think it is fuel issue, use a gage and check proper fuel pressure. There are some other tests you could try, but, too much liability, I can't be responsible for your safety.

dirt put a fuel system cleaner in the fuel tank.

dirty throttle clean with throttle cleaner.spray in the butterfly.

Have them check the camshaft/crankshaft sensor.. please indicate if my solutions are helpful thankyou

Hi Beverly, I believe you may have a problem with the fuel filter or fuel pump. Regards John

catalitic converter is clogged up its not lettig the car breath

they might have not put the proper gap on the plugs..and might have over filled the engine with too much oil..

Your fuel filter is blocked and not allowing enough fuel through. Replace the fuel filter, and the problem should go away.

sounds like your fuel pump is bad, it will sputter or be hard to start because there is no pressure. if it doesn't start have someone hit the fuel tank from the bottom while you try to start it, if it starts right up then you know you need a new fuel pump.

Local mechanic determined engine was flooded and started it by holding throttle to the floor and cranking 5-7 seconds - then the engine sputtered to life. It has run perfectly before and since and I'm at a bit of loss to understand why this occurred this one time - so far. It's been driven now 5 days with no problems.
