i have a 95 cherokee that is not running good ffor some reason
it through a code but havent got it read yet
when i start it itidles real real low
it used to start and run the fast idle ffor like 3 minutes and it would go back to normal but not anymore
if i hold the gas steady at likee 2500 rpms it will bog everyonce in a while but no consistently like a miss
i was thinkin throttle body position sensor or the sensor thats on the firewall any other ideas

Getting the code read would be a great start. most auto parts store will do it for free.

Also whens the last time you did a tune up?

i just did a tune up
no auto shops have obdI readers anymore so that is out of the question
what i did was change the MAP sensor on the firewall and connect all the wires back to it that were supposed to go to it
apparently the dude that had the jeep before me tried making it run off both hydrogen and gas with a switch box
once i took that out and changed the sensor it took a long time to start but after it did its runnin like neew

I woasnt talking bout auto shops, I was refering to parts stores. They have scanners so they can sell you parts. Dunno why they would get rid of OBD1 systems.

Turn your key on/off three times then leave it on (without starting of course). The CHECK ENGINE light will pulse the codes to you. Use this page to see what the codes it throws you means:
