pos 95 cougar need help

[dragon1976]

i have a 95 cougar that is idling at about 3000rpm's. i hvae gone through all the vacuum lines and checked sensors. replaced egr valve per one mechanics thought nd it still runs the same. any ideas??

[ronaldk]

you say you checked all sensors?? what sensors and why?? are there codes?? what eng, how many miles, is eng light on?? did you check air idle sensor , TPS, cruise control cable accell cable it doesn't take much pull on either cable to increase rpm?? maybe I helped who knows?? good luck

it has a 3.8 v6 there is no check engine light on at this time it does work though. i checked the tps, iac, and maf sensors in hope that one was faulty. even checked the sensor that idles engine up when a/c is engaged.

ok it very well could be machanical since no codes. I suggest you remove all cables from TB see if that allows proper idle if it does one at a time return cable lines, one could be sticking not allowing proper return on TB.Good Luck let me know how you do.
