So every once in a while my tach will randomly drop to around 2-300rpm for a little bit then it goes back to normal idle. Just courious on what it could be. I just did the spark plugs and cleaned the throttle body and reset the PCM and it has only done it once since. I have a 06 1500 megacab hemi 147,000km on it
