My 92 Dodge Dak. 3.9L 2 WD just quit running. It sat for awhile before I could fix it. But now I have replaced a section of fuel line, fuel filter and coil. I now have it running but only if I keep my foot on the accelerator at a steady RPM the engine runs smooth. When I let drop to idle speed, it dies. HELP!!!

 

Have you tried your Idle Air Control Valve?

 

No...I am new to getting this deep into a repair. Is that like the idle control module?

 

I put a new battery in and it is running fine. Now when speed approaches 10-15 MPH I get a low pitched vibration the worsens with increased speed. U-Joints?

 

i would check the ujoints, and maybe the tires first, check for a broken bead or maybe have them balanced.
