View Full Version : What's wrong

When I fixed my leafs I removed my gas tank and put new fuel pump in and filter.

First weekend out(toyrun) it was boggy and would kind of backfire if you were giving it gas.

Yesterday it was good when it was cold but once it warmed up it got boggy again but then after 20 sec or so it took off like normal. Then would do it again when let off and hit gas again:dontknow:

Any ideas?

Even idles weird sometimes, since doing motor once and awhile it will almost stall when idling but then rev back up and run normal, but now it's doing it even rougher and actually stalling.

Maybe O2 sensor?

Put your old leafs back in....

That should solve the problem.

Must be another "Jeep thing". :fighting0071:
