Two questions; why doesn't my idle go up with the AC Compressor on, like all other vehicles and why has my rough idle when in gear problem gone with AC on. I know the tach's are usually off a little, but there's no increase in idle with the AC on versus off. I've also been trying to solve a rough idle when in gear problem and just noticed it doesn't do it with the AC on. What gives? It idles at 700 and in gear about 550. I have new wires, spark plugs, coil, TPS, PCV, MAP, IAC motor has been cleaned and checked. TB has been cleaned. No Vaccum leaks and EGR delete. The only thing not replaced is the opti (original) and MAF.
