i own an 89 Cherokee Laredo 4.0
...so i got a problem with my jeep...i took it to a jeep shop and they couldnt determine the problem...he said all the sensors n such checked out....
the situation...
...it takes about 5 seconds of cranking time to start and when it does start it sounds like it is going to choke out and it kinda "gargles" but it starts....
....ill be driving and the jeep runs like crap, sometimes it wont even go over 20 miles an hour....it kinda just putters down the road...i thought it was a transmission problem...seemed like the gears werent shifting but thats not it...
....someone told me it was the o2 (or catalytic converter) sensor....but it checked out.....then the mecanic tells me the sensor is going haywire cuz the engine is running cold which makes the sensor go crazy but that doesnt make sense cuz i ran it without a thermostat for 2 years....
....im thinkin the whole computer might need replacing...
...does anyone kno whats going on?
*UPDATE*
i checked some lines didnt see any clogged or bent but im not sure if i checked well enough....
....couple i things i noticed while test driving
1.) the idle speed is kinda screwy...when i rev it around 4000 for a couple seconds and let it down it idles at 1000 for a few seconds and it works its way to 750 but the needle is hoppin up n down, its not steady......
....then i pop it in drive and the idle goes to around 300, needle still poppin up n down, the jeep sounds like its runnin crappy....
2.) next i noticed when in park the exaust has bursts of air poppin out of the exaust pipe when i put my hand in front of it....nothing major but not sure if their should be no poppin at all
.....when i put it in drive and the idle speed goes down it starts poppin a lot more and a lot harder.......when im drving its even worse and when accelerating it seems acceleration is normal then all of a sudden it slows tremendously and stays at a low speed, it does this at different speeds from about 5 to 25......
FYI.....when in park everything seems great, i can rev it and it sounds good, i rev'd it at 4000 for like 20 to 30 seconds and it didnt skip a beat, when in drive it starts actin screwy, to me (uneducated) it sounds like an air related problem but i dont kno very much (just basics)
