Hello evryone and thank you for any help. I am trying to help my sister out she has a 1995 ford mustang v6. the starter went bad yesterday and it was replaced with a new one. funy thing is that now the engine idles too high and seems to be runing hoter than what it should. I just can not see where her friend who replaced the starter could have caused this to happen by replaceing the starter. any help would be greatly apreciated. thank you Robin
Welcome to the site!!!!I would suggest a good recheck to see if all was connected right and if anything was accidently unpluged.
from what I have been told every thing has been checked over and over again. the only thing that they said was diferent was that the new starter had a different type of conection for the small wire. I can only asume that the small wire was the solinoid wire they say that they had to strip the wires and conect it as the plug was diferent. I can not see how this would make a diference. Any IDEAS?
Did they disconnect the battery when changing the starter? If not, maybe the wire grounded when they stripped it. Maybe check to see if another fuse shorted out.

It's either an unrelated coincidence, or your timing has jumped.

did you notice the idling speed increase the moment the car was started after replacing the starter or did it occur much later? and was the starter reached in from the top or from the underside? asking coz the accelerator cable must have gotten misaligned during the fix. check if the throttle closes properly. if it does, then your problem could be a different one, not related to the new starter.
My prediction: Vacuum leaks, probably around the intake manifold. Listen out for them, they can be hard to spot otherwise.
Finally, if the wiring was done with the battery "live", you could have electrical problems. One indication would have been sparks and startled yelps during the install.
I hope its the vacuum leaks...

that wouldn't explain the overheating (which could be due to a skipped tooth)
Unless there's also an unrelated cooling problem.

Cooling issues... If its not "overheating" (boiling over) it may just be another problem no one noticed until they started studying the car closely.
I wonder if that starter is releasing properly? If its staying in contact with the flywheel... Can't be, on second thought, with the high idle speed. Drag like this would kill the idle speed, not shoot it up.
Not saying it CAN'T be a timing issue, KS, just looking at alternatives in ADDITION to the ones others have listed.

I found ten minutes to go over there today and look at the car. The car idles some where between 2000 and 3000 rpms I for got to look and do not remember the exact number they told me yesterday. It sounded like 3000 to me but I did not look at tack. My sister says it is runing close to the h on the temp guage when idleing for a while but it runs cool going down the road. They said that they disconected the battery before removing the starter. This has me puzzeled as I do not see how a starter replacement could cause this problem. I did check for vacume leaks and did not see any. I would have thought vacume leak my self. I tried to lower idle speed but that did not help. Could a senser be bad or the timing jump but I would not think timimg but I can be wrong
IAC valve? how would I test it? If it was bad would it show a code? I was told that they disconected some of the sensers and it did not show a check engine light.
Replaced starter now it idles to fast
