Did some searching and not quite sure how to proceed. I've got an 88 10AE with 83,100 miles on it. The car idles fine cold, and drives fine. When it warms up the idle seems choppy, like its infrequently missing. Outside of that, the car feels smooth and drives very good. I was wondering (outside of plugs as I am about to change those) what are the likely culprits. Car is bone stock.

Well its pretty hard to diagnose driveability over the internet. This problem could be cause by many different things...the first thing i would say is do a full tune up. Including TPS adjustment and idle speed verification. And what fuel do you run?

its a turbo 2 so i run 93 octane mobil. its intermittent and sometimes just vanishes. i have changed the oil, transmission fluid, rear differential fluid, brake fluid and coolant as well as the spark plugs. coils and wires look fine but the car only had 2000 miles put on it between 2005 and today prior to me buying it. it drives and cruises very nicely. just has an occasional choppy/misfire idle condition.

i will look into testing the tps and change the wires.
