ill be driving cars warm the come to a red light idles fine the very slowly starts surging from 800k-600- starts slowly then it will go alil faster now it only happens after a 30 secs of sitting there if i got to a stop sign quik idles fine but when stoped for 30 secs it starts doing what i stated ive done everything no cel gaskets idke relearn cam timing ignition time iacv fitv idle relean coolant compression test everything an now i think its something to do with my harness there is 2 wires i dnt understand that dnt match up to what i read onecu pinouts if i slap the wires the idle will jump up if i bend it will surge if i leave it it does wat i said above thank yu for any help or advice seriously
