Ok after going over the car today i found when i started up the car was idleing at 900 when cold, when warmed it was at about 12-1300. I started fidling with some plugs on the throttle body pulled one out and the revs went up to 1600 i plugged it back in and they stayed at that, so i went and pulled another and the revs dropped to 900 but was running very rich (popping when letting of revs) i plugged all back in and they stayed at 15-1600. The car also needs a very good full service could this have anything to do with it? Could someone post a pic of a 4efe engine with a circle round each senso
