Well I would just like to let everyone know that tomorrow I leave for Ft. Jackson. And then I will be heading to APG to train to become a 91B or wheeled mechanic. So thanks everyone for all of your great info on the OBS trucks.
I did disconnect the battery when I put the new iac in. And I have put around 50 miles on it since then. It still runs rough but only when it gets warmed up, now that I replaced the iac. And know cel has come on yet.
Ok so now the tahoe's symptoms have changed. When its cold it runs smooth and dosen't miss a beat. But when it gets up to operating temp it starts to misfire and run rough.
Well I got the new iac in, and reset it. But it still misfires a runs rough. This truck is driving me crazy. To me it seems like it has gotten worse. So now im leading toward a bad coil or ignition module.
Well i finally replaced the tps, and disconnected the battery. At first it ran better. But when i git back from a 40mile trip it started acting up again. No codes yet. But it still misfires and tries to die. Could maybe the coil be going bad or is bad?
yeah thats what i came to think. Was that someone was missing a cover. I know it didnt fall off because its a habit i have to look at them when i get out of the truck.
