Engine Performance problem
1997 Plymouth Voyager 6 cyl Front Wheel Drive Automatic 128000 miles
I recently changed the transmission and my engine that ran great started to miss. I removed the upper intake phlenum to change the rear spark plugs and when I put it back togather the engine shoots right up to 4 grand at an idle. I have looked for anything that I might have missed on assembly but I can't find anything. I disconnected the TPS, no change I disconnected the IAC, nothing. There are no trouble codes, but I haven't let it run very long, just long enough to see where the idle is and shut it down. Please help, I have seven kids and getting them around is getting very hard.
