July 27, 200520 yr I have a 93 Justy with 103,000 miles. It has a hesitaion that doesn't appear to be tied to RPM's. I changed the Fuel Pump, but that wasn't it. It never does it at idle, but at every speed it does. Very intermittent, and getting worse. I have had three tune-ups since this started with no improvement.
July 28, 200520 yr Fuel Injection or carb? Since its a 93 I assume FI... I would try replaceing the ECU coolant temp sensor or atleast checking to make sure of the connection and function. If not that...possibly the MAF or MAP's operation and connection.
