jimbboise Posted July 27, 2005 Share Posted July 27, 2005 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. Link to comment Share on other sites More sharing options...
WJM Posted July 28, 2005 Share Posted July 28, 2005 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.
