This is my first time here on this forum. I just purchased a 1987 Mustang LX 5 Spd and there is a problem with the tach. When i start the car it shoots up to 2500 RPM and stays there. Im not sure where the wiring is for the tach and i can't find anything on the net or my repair manual on how to fix this problem. Any ideas.?

 

welcome aboard..go to the library and get the motor manual

 

Well ive been to the library and with just my luck they had every book in the world except for the one i needed. Can some one tell me how the tach hooks up to the motor or where.

 

How do you know the car doesn't have an idle problem and isn't really idling at 2500 RPM?

 

yea... you'd think you'd hear your lil 4 cylengine revving up.... even tho its reallyonly half an engine.<IMG src=smileys/smiley2.gif border="0">

 

hey i had the same problem in my doge truck. it would shoot to like 3000rpms then do nothing. i finally took the dash apart and i found the needle was rubbing on the guage cluster i bent it a little and it is fine now. hope it helps

 

damn wouldn't know it...the above sounds like a start
