Been a member here for a while, but have been lucky enough to not need to post any questions. I'll try to be thorough with my issue, please forgive me and point it out if I miss any important details.
I have a 93 Cherokee 4.0L (150k miles or so) that's gotten cranky lately. I don't drive it a lot, 3-10 times a month. And occasionally it will give me a hard time starting up. Just making a clicking sound initially when I turn the key, then slowly starting to turn over, this usually takes about 1-3 minutes to get going when this happens. Then it is usually fine.
This happened yesterday, since it's happened before I did not think much of it.
I was VERY low on fuel, so I filled the tank. Then drove for about 60 minutes in stop and go Seattle traffic on a hot day (no AC, good times). I was crossing a bridge doing about 60 MPH when the Jeep died, the radio and lights stayed on, but the car was stalled. No indicator lights, no symptoms leading up to it. Fluid levels all fine. Radiator is about 18 months old.
I sat on the bridge for about 10 minutes, then got it going again and was able to get off the freeway. It gave me the same cranky startup as it had earlier. It stalled 2 more times en route to my destination.
Once I got to where I was going. I checked for a diag code. I got "12" and "13".
"12" appears to be the memory clearing, and "13" has to do with the MAP sensor.
I found a few posts online discussing similar issues. The fixes ranged from fuel filters to bad spark plug connections resolved with contact cleaner or WD40. My regular mechanic who I trust suggested it could be the crank sensor, and I found a post here covering a similar issue where the crank sensor appeared to be the culprit.
It does seem like I may have 2 separate issues.
I am not a mechanic, I am a computer and audio tech by trade, but I am up for trying things myself, within reason. If it is the crank sensor, that is something I'd prefer to have my regular mechanic do. But, if it's worth trying some other things before taking it in, I'm up for it. I've got the Chilton manual, and can get my hands on some basic tools. But I'll be quick to admit when I'm in over my head, I certainly don't want to make things worse...
Sorry for the long winded post. Any suggestions appreciated. Even if it's "You sound like a noobie and it's over your head. Take it to the shop!"
