The reason I rejetted richer, was because of the lean indications of the spark plugs second to last time I changed them. The pop was present before I rejetted. If it is excess fuel in the exhaust It still does not explain why it seems to cut out and loose power when it pops. (or does it?)
If it acelerates slowly it wont pop as often
If im stopped at ground level I can kick it and it screams with out a pop.
When I am heading up the hill, I drive on my way to work, If I punch it, it will pop/sputter. If It kicks down a gear while passing it will pop/sputter. It definately feels some power loss while it is popping, not just noise.
Maybe this is a dumb question but, I installed a fairly cheap electric fuel pump, and mounted it next to/under the driver seat, I did this so I could hide a switch for anti-theft (dont tell anyone, after all it is a soft top Jeep) I have heard that electric fuel pumps should be mounted as close to the tank as possible. Could this probelm be from to much/too little fuel pressure?. It does'nt seem likely to me but, Im sorta dumb sometimes.
