Help me im scared?

i have a 87 mustang gt, and it feels different starting yesterday,


it rumbles more while in i idle if im not stepping on the gas the clutch moves more and the wheel, the rmp needle stay a little below 1, im assuming thats healthy, i put in a new alternator a month ago and a new power steering pump about two weeks ago, i dont think that has anything to do with it, im just stating it just in case it does, its just weird how its rumbles more, if i floor it in neutral the clutch shakes and moves to the right, im not sure if it was doing that before, but yeah its got me concerned so opinons are appreciated thanks

Sounds like the clutch may be slightly engaged even when its pushed in. Try adjusting the clutch cable so that the clutch enguages when the pedal is farther off the floor. Also inspect the motor and transmittion mounts as that could add to the shakeing.

The best thing that I can suggest is, that if you are that concerned about your car, take it to the mechanic and have it looked at.
Reply:Nice call, Andy.





As a means of checking further to see if it's the clutch, try starting the car in neutral so there is no gear to drag. Since the car has a neutral safety switch, you'll still need to have the clutch engaged when firing it up, if the idle smooths out when you release the clutch, the clutch is your most likely suspect.





The throw-out bearing might also be going away.





I had a friend with a manual transmission Mustang that started to do something like you describe, but for the oddest of reasons. He was known for literally stomping the clutch pedal and the holes where the pedals pivot from were rounding out until his clutch and brake pedals slid in the now-oval anchor points and caused a problem like you describe. Yeah, that's an extreme example, but if it happened once...
