i think it's running lean at idle but good at high rpms. and did they have o2 sensors in 85? i'm not sure if this truck was pieced together or if it was converted to fuel injected or special ordered or what?. i'm thinking it was converted well a good while ago. and now it just ain't quite right. i don't think it has a cat either. but the valves do tap pretty bad. we've been using it too much to tear it down any. low range rpms run pretty bad. ESSPECIALLY under load i'm starting to think we just need to go get an l-6 but like i say before i put too much money into i'de buy a 2wd highway truck.
