A "pulling feeling" ain't gonna get an answer... We need to know what a "pulling feeling" does to the Jeep. What does it do?

Your gasoline tank vent may be clogged. Try removing the gas cap (seriously) and running for that 2 miles or so, and see what happens.

the pulling feeling sounds like brings my engine to idle and and im not getting very much or sometimes any gas but it never really stalls

Change the fuel filter and go drive it!

i've already changed it but i drove for about 3 miles without my gas cap and now its running way better, but what did that do<img src="/forums/images/graemlins/confused.gif" alt="" />

Some gas tqnks vent through the gas cap. There must be a vent, or else the fuel pump will eventually create a vacuum in the tank, impeding good fuel flow. If you take the gas cap off, and it runs better, it's an indication that the gas cap vent may be clogged. Sometimes, just banging the cap around when you're removing and storing it will clear the vent, and it will work when you re-install it. But if it starts running bad again, invest a few bucks and get a new gas cap just to eliminate the cap as a possible cause of the problem.

A partially clogged fuel filter can also cause a similar problem. If you have both a bad cap and a partially clogged filter, you can get some weird indications.

Given the inexpensive cost of filters and caps, I'd change them both and monitor the engine operation for a while.

ok cool thanks alot <img src="/forums/images/graemlins/kewl.gif" alt="" />
