Hello and welcome! My name is ***** ***** I can assist you with your question. Is the check engine light on? Are there any codes in the computer? Does it stall out at times when ilding or driving?
Thank you for that information. The most common causes of a rough running condition on this engine are bad tune up parts, bad/weak fuel pump or even a bad camshaft position sensor or crankshaft position sensor.
You are going to want to check for air or vacuum leaks under the hood as well
The TPs (which is the throttle position sensor), oxygen sensors and MAP sensor can all affect how the engine runs.. but these are less likley to cause this issue you are having.
When was the last time the engine was tuned up?
IF it has been a while, you might want to start there.
Dont forget about checking fuel pressure and the cam and crank sensor. YES, check near the intake manifold and gasket, and the throttle body and gasket.
Be sure to check all vacuum hoses and vacuum lines as well. They all get engine vacuum from the intake manifold.
So if one of them are leaking vacuum, it can and will cause this sort if issue. It might just be that simple.

Thats correct. It would take the computer a while to trigger a code related to this issue. Are you asking me what code it would flag if there was a vacuum leak? It would be a P0171 lean code.
That is from the computer when it sees the oxygen sensor too lean for too long.
The vehicle needs to be driven.
That all depends on the issue, the severity of the issue and other factors. My experience has been that the computer will pick up on this problem and flag a code after 2 or 3 days of driving.. maybe sooner.
YES, I would prefer to speak on the phone rather than chat on line.
You can request a phone call right now if you would like.
I can talk now
Ok sounds good! I do ask that you rate my service now for answering your questions.
We can do the phone call thing later after you get the codes.
