2.8 mpi '89 Cavalier has a slight but noticeable miss at idle, runs
pretty much normal otherwise.
Plugs & wires replaced recently, new computer, several sensors (TPI
and I "believe" MAP).
Seems to hesitate slightly off-idle when taking off (manual trans).
Miss seems to disappear at engine speeds greater than idle.
Still gets the same gas mileage.
What is likely the cause of this?
