I have a 94 EF Fairmnt Ghia I6.
I have a probelm, when I start the car, the revs sit at 1,000 for ages, then eventually drops to 750. Even when sitting at 1,000 and i put it into D the revs fall to normal, then back to P, the revs climb back to 1,000 for a bit. Sometimes this doesnt happen, but its happening more and more.
I cleaned out the throttle body and ISC, what else can I check?

Thanks

It sounds like a sticky ISC or the base idle is set a tad high. To clean the isc just undo the 2 10mm bolts and unplug simple, then just give it a wack with carby clean. Once cleaned reinstall and get the engine up to operating temp and sit there in park switch to D etc to check it if still doing it wind out the idle adjustment screw a small amount. Alternativly like Topghia said get the codes out.
