    Default It feels like someone is turning the key off and on...Help Anyone?

    Replaced Opti with the Torq Head 24x. Before this I had issues with misfiring intermittently after 10 minutes of warming up. NOW...This is not a misfire. Car runs great and idles ok but every once in awhile (or sometimes more often it) engine will turn off for a second and then back on. It will do this over and over and then run great again. It does not stumble or misfire or run rich....it is just like someone turned the ignition off for a second or split second. The gauges do not turn off and their is no engine codes to indicate anything is wrong.

    This is all after I had it in the shop and installed the Torq Head 24x complete kit, mass air flow sensor, battery, new spark plugs, and they are still scratching their heads. Wiring seems to be the culprit but we cannot seem to pinpoint the problem. Anyone else have this problem?

    Have you checked the harness going into the back of the PCM? I swapped the (411) PCM in my truck once and it started doing weird things like that - the plug wasn't quite seated perfectly in the back of the PCM even though the bolt was snugged down. I just wiggled it around and pushed it in a bit more and it solved the issue.
