I have a 93 with a 5.8L. I bought it thinking the tranny was bad but after checking the cel, just ended up being a tps. Also had a code for egr but the light went away after I installed the tps. Now, when you first start it, it idles normally, but as soon as it's warm, it idles at 1500 or so. No cel but I haven't scanned again to see if theres anything else stored. Any ideas?

 

Sticky IAC valve?
