Why does my engine hesitate during acceleration ( cel )?
Check the Manifold Absolute Pressure (MAP) Sensor If a bad sensor is causing your hesitation issue, it may (or may not) trigger the check engine light (CEL). So, before you begin any diagnostic procedure, it is a good idea to scan the computer memory for trouble codes that can help diagnose the problem.
What happens when you hit 3000 rpm in a car?
If you are driving down the highway or taking off from a stop and hit 3,000 RPM the car will stop accelerating and the gas pedal basically becomes non-responsive. The car then slows itself down until you are under 3,000 RPM at which point it will perform normally as long as you stay under 3,000 RPM.

What causes an engine to idle up and down?
A malfunctioning MAF sensor can cause a wild up/down engine idle speed (say, 0-2,000 rpm). This might be caused by a loose harness connection or by a damaged or contaminated sensing wire. The MAF sensor measures the amount of air flowing through the throttle valve.
