High Idle, Check Engine/Traction Off Lights, No Speedometer
I am new member to this forum, first post, hope somebody can steer me in the right direction.
Here'* the situation: 94 Bonne SE
A few days ago my Check Engine Light came on, along with the Traction off light and my speedometer no longer works. My Immediate thought was "It'* just a glitch" So I pulled over shut the car off and hoped for the best. Wouldn't start without a jump. After I got it started, I took off, but still had the lights, no speedometer, I headed on down the road and the speedometer came back for a few miles and then went away.
Along with this I have a high idle, sometimes a tolerable 1100 but sometimes it races to as much as 2500 or so, not good.
I drove the car over to a good mechanic to have the codes read. His computer could not read them, nor could the one at AZ, and Advance. The mechanic did a little tinkering and caused the Idle to go up while tapping on the throttle body and was quite sure the IAC plunger was stuck. So I swapped throttle body, along with the IAC, TPS, and MAF from my '92 which ran perfectly everyday it was in service (frame and body rusted). No help.
Also I put a new battery in, since the old one was shot. I think maybe this may have started or led to some of these problems, but not sure.
Any suggestions greatly appreciated. I have a complete parts car so swapping parts to test is no problem.
Sorry for my wordiness.
