Is the check engine light on while the engine is running ?
If it is I would start there for clues.
If not, the list of possibilities is long.
You should check the fuel pressure and probably the throttle position sensor resistance. It could have a vac leak too.

1996 mustang 6 cylinder. trouble code says either gas cap (we replaced that already), fuel return line( checked it, didn't find and cracks or breaks that I could see), or possible vaccum leak (not sure...

Hello, There is a test called the "smoke" test which is done with a machine they hook up to the gasoline venting system. You could easily have a leak under the mounting straps for your fueltank.

The "smoke" test is the best way to find difficult leaks. Also remember to clear the light Code from the computer, it would take 25-35 Startups to clear itself.

Without clearing the Code, you may have already fixed the problem and don't know it. Sometimes you can clear the computer by disconnecting the NEG battery cable for 10 minutes. Some clients have radio problems after doing this, so I recommend going to Autozone, Oreilys, or Advance for a free scan and to clear the computer.

95 Buick park ave is stuttering when pressing on gas pedal. Tuned up still doing it. No check engine light puzzled?

Use brake clean and clean the inside of the throttle body. open the valve and clean the back of the plate and inside the throttle as best you can, use a small brush. If you have a Mass air flow sensor clean this also. don't use a brush on this. Once you clean those , start the engine, may take a second. then spray some of the brake clean in the throttle at higher RPM's. This should help your problem. Let me know

Got 1988 buick park wouldnt start,hooked

You may have damaged the starter when the engine kicked back.

The ignition module may have been defective.....but change the crank pickup too.........more likely it is the cause of the problems.

Change the crank pickup at every tune has a high failure rate.

If your engine has 250km or 150K miles you may need a chain soon.

1998 Buick Park Ave Speedometer stopped working.

Found the problem with the speedometer on my Buick. When you use the magnet to fix the gas gauge, will can and may affect your speedo. So use the magnet trick on it as well. Appears that the manufacturer didn't think about the needles being able to swing past the magnet they have set up in the gauges. Should have put a stop pin on the gauges.
