My 92 3.0l basically just sounds like its got a cam in it all the time! When its first started up in the morning it doesn't really like to stay running, ESPECIALLY if its below 50 degrees outside. It'll also surge from 1500rpm to 600rpm when I come to the stop sign a couple miles from my house. Once its warm it'll stay running and won't surge, but it still has that lumpy idle.
So far I've put in motorcraft plugs (it got a cap and rotor within the last 40k), a new coolant temperature sensor, swapped the MAF with a smooth idling truck, cleaned all the intake sensors I could find, but it still does the same thing.
Really other than the idle the truck runs like a champ and hasn't thrown any check engine lights *knock on wood*..Its been doing it since my friend bought it with 94k miles, its got 142k now.
