So the past two days I tried starting my 96 xj and it tried turning over but just couldn't. walked out this morning and she shot up the first try. However it was pretty rough at IDLE while I was in park. Took it around the block and it was kind of hiccuping the whole time. And also while I was in idle i heard tiny reving sounds coming from the muffler but my rpm stayed the same. Any ideas?

 

having the same problem on my 97. i just replaced my cap rotor and wires seemed to help but we will see tomorrow if she wants to start. when you key your jeep on does the check engine light light up?

 

Nope, All lights gauges work perfectly fine. And I too replaced the cap and rotor. Because the day it stopped running fine the weather here warmed up from 17 to 54 in a day and all the snow melted. Figured some moisture got underneath so I replaced it. Did nothing though. A few friends have told me to check either the CPS or the fuel pump? but I have no clue how to look at these things

 

no way man same problem! and that was the same day my stuff didnt work i live in chicago also. then last night she started up with it was dry and cold

 

Man, this is crazy haha. At least I know I'm not the only one. But when you got yours started up was it running rough?

 

at idle its a little rough. i went to napa in melrose park and it made it, picked up a cps but im goign to wait to install it and see if the problem is still there.

 

So you think it could be the CPS? thats what my neighbor warned me about too. Was it running rough before that night? Mine was running just perfect, but when I started it up today it wasn't running so smoothly.

 

yup same thing. the night before it started right up and then the next day it was wet and warm and she didnt start. it sat for 2 days and started right up. it is a little rought but not bad. im thinking its the cps. i was scared mine was the computer but im goign in the garage to see if my check engine light bulb burnt out

 

Sweet. Let me know what goes on with yours because I bet we have the same problem. Also how uch was your CPS? and do you plan on replacing it yourself? Or taking it to a garage?

 

it was 87 at napa. and im doing it myself.

 

well found out that my check engine light was burnt out so i replaced it and i had two codes one for the crank sensor and another for a o2 sensor. i cleared the codes with a scnner and drove about 15 miles with nothing coming back on so we will see what happens

 

I'll have to check the same. I'm almost positive my light works, but if not how did you did you check? and how did you get the codes?

 

i had to take my gauge cluster out and swap a bulb around to see if it was blown. and you need a code reader to get the codes. you can bring it to an autozone and they can check for free. but since my light was out i didnt see the codes. i cleared them and shes still starting and running fine
