I have a '98 Auto, 4 cyl, Jeep Wrangler, 140k miles. For about 2 years it has been hesitating in low gear. when I press the gas it's like there is no fuel getting to the engine because it does not accelerate and then all of a sudden it will lurch into gear with a jolt and drive fine for awhile. It used to also misfire when hesitating and sometimes stall when idling. New spark plugs and a new TPS fixed these two problems but it still hesitates. I have also had no heat for about the same amount of time. The heater only blows luke warm air and takes a moment to switch through the different settings on the dash. The temp on my gauge says it's only getting up to 120 degrees... 170 at most when I'm on the highway or driving up a steep hill. When I replace the thermostat the heat will be a little warmer and the temp gauge will read around 190 degrees for awhile until the t-stat fails again. I've been through 3 in less than a 2 years. Are these related possibly? I was told by someone that it could be a vacuum leak? I'm a girl in my 20s and know very little about Jeep engines. Please help!

check idle air control, tps & map sensor. As usual with electronics, test test test before buying anything/

probably neither. You should do a compression check, and check your transmission fluid for dicoloration and metal shavings.
SOURCE: Holds idle fine but stalls when accelerating
your carburetor should have a fuel filter in the carburetor body where the
fuel line enters it replace it and, any other in-line fuel filter the engine might have
