100993, Car missfires at 4k rpms Posted by ohyeah2, Sep-17-06 04:58 PM 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? | |

100997, RE: Car missfires at 4k rpms Posted by xcasbonx, Sep-18-06 05:20 AM Check or replace your MAP sensor. If your cars stuttering at 4k rpm then this is most likely the culprit. | |
