I have a 1995 GMC 1500 that is not running so well. It has an oscillating idle when in park, but only SOMETIMES not always. It seems to be idling high pretty much all the time. It stalls here and there, and is really sluggish off the line. Also I have a check engine light that comes on and off. I have brought it to a dealer to have the codes read, but the check engine light went out before I could get there, so no codes came up, and there where no codes stored at all either. I have put inn new plugs/wires when I got the truck about 4 months ago, also changed the oil/filter and fuel filter. Removed the EGR and IAC and cleaned them. I'm about to burn this thing to the ground any help would be great!! THANK YOU!!
