Forum has spell checker. The dot on the key with the symbol . and > is a period.

 

'96 has OBD II so you should be able to have it scanned and see what issues caused the CEL. Its 15-16 years old, so it could have various issues depending upon how it was maintained. Coils are known to break down, but the throttle position sensor seems like it might be the culprit. Has it been checked ot changed?

 

Replace your crank sensor.. I bet that's your problem.. Mine was cutting out like your saying.. It would cut out and come right back on while driving randomly..

 

Unfortunately betting costs money and most of the time doesnt fix the problem. If you have a step by step procedure that will show its the sensor then post it up.

 

Only cost money when your wrong..I sure don't have a step by step procedure to show its the sensor. I do have 1600 miles of random cut outs on my jeep driving it from miami to iowa.. I replaced my crank sensor and has never done it again.. The guy I bought my jeep from had no clue either. He thought it was bad gas....

 

it has a new crank sensor that was one of the first things i tryed the scaner just tells me the up streem 02 is runing lean i have a air fule gauge on the down streem and its all ways runng rich but when i changed the up streem o2 i ran good and the air fule gauge was reading like it should then it just went back to **** again like how i didnt use any .... agian

 

why comment if you have nothing to say about the topic?

 

Please stay on topic guys. As for the content of your posts, I have always felt that you get out of them, what you put into them. Meaning, if someone spends the time to make a proper post, I will tend to be willing to read/help more. I simply will not read a post that is typed like a text...

Maybe ya put a defective crank sensor in it? I've seen that before. Did you buy from a parts store or stealership? I'd say its defective and try a different one.. Its an eazy swap.. I have had better luck with electrical parts when bought from a dealership.. I honestly think that's your problem..

 

Well, I'm not going to avoid trying to help someone just because maybe they don't write as well as I do or care as much about punctuation as I do. If someone's broken down on the trail with two flats and one spare, I'm not going to drive past if he says, "I ain't got two spares."

It seems like every time you replace something, it works for a while, and then goes to pot again. Have you thought about, say, pretending to do one of those sensor replacements again? Like, disconnect the battery, pull the sensor, and then put it right back on, and see if the same thing happens.

My other thought is to check all the sensors one at a time with a multitester, or replace them all. Sounds like a lot of work, and it is.

One other possibility, which fits your symptoms but not your description of events: your fuel filter may need replaced [cheap] or something might be wrong with your fuel pump or its wiring [not cheap]. If you replace the filter, cut it open: if there's a lot of sand and such inside, drop the tank and clean it out. I pumped gas for months from a cracked tank and filled my tank with sediment, and just kept filling filters until I realized the problem wasn't going away.

Last words: I know this is frustrating, but don't blame "Jeep" for this: any car can have difficult-to-trace intermittent issues, particularly at this age. My Jeep has been more reliable than the BMW I sold to buy it, but yes, sometimes sensors have gone bad and been tough to track down. But I'd driven a long line of cheap old cars, and the Jeep is by no means unique in having such problems, and it's in fact had fewer than any other I've owned. Stick with it: it's worth it.

 

Cool cool thanks for the advice. Don't mean to bad mouth jeeps just getting frustrated with it.
