If I have to press down far on the gas pedal to get it to go at a somewhat decent speed, could that be my tps? And the cause of my 7-8 mpg? My jeeps always been "slow" now I know it's not a race car but compared to my sisters 96 xj with 216k it's slow as @@@@. Feels like its just sucking the gas while there is no power going. It's a 94 country with the 4.0. Also sometimes when I'm trying the speed up sometimes the tranny might stick at 2500 rpm and then shift a couple seconds later. New o2 sensor, fuel filter, recent tune up, fresh oil, air filter. It's been like this for awhile.

...my '96 just started doing something similar (I put a new cat' on a couple of weeks ago). I was going up a slight hill near the house, and it was ...weird. Different than every time before (which was press-and-go); wondered if it was the ECU getting to know the new cat' (this was maybe the 3rd or 4th drive since the new cat'); kind of felt like a sudden loss of power at the time??? Since, I'm having to punch down to get the oompf.

I checked them they are not sticking. Also I now have high idle after I put it in park. It jumps up to 1100 and stays even if I step on the gas. That happened after I changed the motor mount on the drivers side..
