just recently had my car in for a tranny rebuild.....now the engine's running rough at low RPM's.....they found one vacuum hose off of it, but it was put back on and it's still running badly....at wide open throttle it seems fine.....computer's not throwing any codes.....i don't know what's wrong with it....it's an 88 5.0 TPI.....any help would be great.....this is driving me nuts

 

someone please help......i'm going crazy here...it's such a nice day and my car's running like an import....why why why?

 

I don't know if this is the same thing but I had my Tranny go in Nov and when I got it back it vibrated during idle so bad it loosened your teeth. I went back and got the blah blah blah crap you would expect, we did nothing that engine is so tight its low tolerances. I when under and found that the pipe clamps on the Y-pipe to the headers where loose and had moved around a bit and banging against the cross member under the oil pan. I moved them and tightened them up and it’s gone away.

Don't know if this helps but I know how you feel man. I hate it when I have to let others touch my car.
