for a little while now when i start my truck the rpms jump up to 800-900 then for a split second, if that, drop down to about 500 and then shoot right back up to normal 800-900 idling rpms. This whole variation in idle occurs over a total of 2 second max. Is this normal and I am a truck hypochondriact or could there be something screwy? It doesnt happen everytime, maybe 1 outta 5 if even that often.
