irradic idleing
 

ok, on cold starts, my egine rpm's will go up as normal, then come back down to normal, but then the rpm's will go up and down about 150-200rpm's, once i drive and get the engine to the normal temp, the rpm's is still a bit irratic but only about 50rpm's up and down.( 4.6l 3v-vortech V3 S trim-has very good tune on it-36k on it.)
Anybody possibly know whats going on ?

bump.
