1989 1500 350 stumbles at idle
Hi all I'm new to the forum and glad to find it. Hope someone can help me with a problem I have with my truck. My truck runs pretty good except at idle and in gear ( automatic ). It stumbles then clears up then back to stumbling. Seems like some sort of vacume leak. I thought it was the EGR valve but a new one made no differance. I also changed the EGR solenoid and that made no differance. Maybe someone has something I could try. Thanks, Charlie

charlie you might be able to try using an aerosol lubricant like wd-40 spray around in different areas under the hood taking your time and listening for a change in the idle then search that area for your vacuum leak. but be very careful that you dont cause a fire.
