pederl Posted November 4, 2010 Share Posted November 4, 2010 Where can I find a test connector for my 1989 jeep Comanche? I have a Vetronix tester model tech 1A but none of my connectors will fit. Link to comment Share on other sites More sharing options...
Automan2164 Posted November 4, 2010 Share Posted November 4, 2010 Where can I find a test connector for my 1989 jeep Comanche? I have a Vetronix tester model tech 1A but none of my connectors will fit. The only two test connectors are under the hood, by the pressure bottle for the coolant... And they won't give you much. '89 Was WELL before when the ECU's started doing the cool stuff. Rob L. Link to comment Share on other sites More sharing options...
pederl Posted November 5, 2010 Author Share Posted November 5, 2010 The truck is running but it runs like crap, I have to keep giving it gas or it will die. I have changed the plugs, wires, rotar and cap, fuel pump. I has to be a sensor, correct? Link to comment Share on other sites More sharing options...

whowey Posted November 6, 2010 Share Posted November 6, 2010 vaccuum leak? Check around the IAC also. If it comes unseated for any reason it will cause the same issue. Link to comment Share on other sites More sharing options...

Geonovast Posted November 8, 2010 Share Posted November 8, 2010 Idle Air Controller, it's a valve in the throttle body next to the TPS that lets air in when you're not touching the gas pedal. Link to comment Share on other sites More sharing options...
