Whats up guys? I got an 86 GT and it's runnin rough, somtimes. It seems to sputter at red lights and at a steady speed. When I give it gas while driving it runs great. I put new plugs, wires cap and rotor. no change. also after driving when i put it in park it idles at 1100. Do you think it could be an injector that is dripping fuel?
Thanks alot.

does it have a vacuumm advance on it

 

run a koer test and check for codes, if that yields nothing look for vaccum leaks and make sure the egr isn't partially hanging open.

 

No vacuum advance. It's TFI.

 

I don't have any access to test equipment either.

 

just check for vacuumm leaks thats what it sounds like to me my car was acting like that a coupla days ago

 

I have the day off tomarow so i'll check.
Thanks alot. I'll let you know what I find.

 

using the koer test function perform a cylinder balance test and see if any code indicate where a misfire may be

 

Some vacuum lines look questionable. I bought some new lines but I ran out of time today. I'll update this weekend. I'm going to pull the upper plenum off and check for a leaky injector too. My concorde had a simillar problem that turned out to be a leaky injector.

 

changed almost all vacuum lines and no change in the way it runs. I tryed to get the 5.0 plate off the intake but I can't get the damn screws to crack loose? got any tricks for that?
Thanks!
