Howdy folks,</P>


I have had a very trouble free '99 durango with 140,000 miles racked up on her. Lately, however, when the car is idle, it will occaisionally "jolt." or "miss" I dont really know how else to put it. Anyone of y'all knows what is going on?</P>

 

First thing, do a tune up... Spark Plugs andWires,Cap and Rotor, Fuel Filter and maybe change the oil for good measure... and see if it still happens. Is the engine itself missing, or is it just a vibration type noise you get randomly at idle?

I second the thought LOL

but while your at it...why not do some upgrades too!! LOL

MSD 8.5mm....or Accel 8mm, NGK or Autolite plugs, any BRASS cap and rotor, and an Accel or MSD coil will get you about 1-1.5 mpg...and better throtle response!!

 

I agree!! lol! I was just trying to get the problem. LOL! ALWAYS consider doing upgrades... and when something's not working right, that's usually the best time to do so. LOL!

TRY AN O2 SENSOR SHOULD BE ABLE TO CHANGE IT UR SELF AFTER THE OTHER TUNE UP SUGGESTIONS.

 

the other thing I just thought of...clean your AIT motor at the back of the Throtle Bodie!!

It controls your idel under different loads.

If it has built up gunk the plunger wont move.
