My 1989 t-bird has picked up a intermitent tmiss at idle. So far the mechanics have tuned-it, removed and cleaned fuel injectors, new fuel pump,fuel relay. The computer shows no codes, the map sensor is fine, the scope does not pick up the miss , but it is there. We are a dead end any ideas would be appreciated.
Too bad I can not drive the cobra every day to work.
Any help or direction would be appreciated.
thanks
Rich
