#100993, "Car missfires at 4k rpms"


          

The other night my car was idled real rough. I have replaced the spark plugs, wires and the ignition coil. It idles and runs fine now until about 4k rpms. Then it feels like it misfires, dosen't want to get up and go anymore. What could my problem be?

Do you have any check engine lights? Are you turboed or still N/A?

Check or replace your MAP sensor. If your cars stuttering at 4k rpm then this is most likely the culprit.

I've had similar problems. the first time it was a bad plug wire. All the other times it was the map sensor.
