History on this car:

1990 Dodge Colt GL Automatic
53,000 miles. Garage kept.
Averaged about a thousand miles per year for the last 10 years.
Bought this car Cheap because of a bad ECU.

Things I have done since I bought the car.

Cap, rotor, plugs,wires, fuel filter, and ecu.

I have the same issue with a known good ECU.

This car has a miss at higher rpm's. It runs great till approaching 50 miles an hour then I get the miss.

Any thoughts will be greatly appreciated!

George

Check the boot of each spark plug and if you have any that are white or grey, you dont have a good tight connection. Sorry, its hard to trouble shoot a problem if your not there with the car!! So that's my guess. :oops:

I'd try a different MAF.
