Idles high in park , about 2100 rpm, seems to do fine while driving but don't have to give it much gas, at stops - shifts down hard
Its either a faulty idle air control valve or a faulty fuel pressure regulator.My bet would be the idle air control valve. If you pull the vacuum hose off the fuel regulator or the map sensor and fuel runs out then the regulator is bad.If you replace the control valve then you have to reset the computer.
