warm startup idle issue

[jfgibb1988]

Hi I have a 1988 w/ stick, 4L 6cyl that always starts fine when cold.  However, when the engine is warm and i start it the engine will sometimes rev to around 3K rpm and stay there...i shut it off and try again.  Sometimes once - sometimes 3 or 4 times.  It doesn't happen every time i start it warm, it will go months w/o the problem and then it returns.  I have tried sealing all the vacuum tubes and air intake around the air filter.  Any ideas?  thanks!

Very likely your TPS is bad.

 

That said, have you done Tips 1 through 5 yet?
