are you having a problem???

95stang gt

um kinda. every time i re-time it i pull that plug ur supposed to to time it(forgot the name of that censor) and every time i plug it back in it goes back down to 600. i cant figure out why

mjr46

it's the spout connector.......set timing with spout out......then perform a base idle reset

yea thats what i did. ill disconnect it and time it and every time i plug it back in the computer resets it to 600 rpm. it was never that low till about a month ago. it always sat around 750-800 rpms

run a koer and make sure that no IAC codes are presesnt

The U/D pulleys you have might be part of the problem. Either swap out the alt or put the stock pulley back on.

and Boss Hotrod it never did this before and ive had the pulleys on for over a year now
