Hey thanks for the input!

Well I've never had the timing belt replaced myself, but the previous owner was it's first and only owner. He said that it was replaced at 60k, then again after it failed but miraculously survived at 120k. Currently it's around 142k. Considering that this issue seems to occur only a couple of times every 3-5 months would you still think that this is a timing belt issue?

Those in between times are great and the car seems to run perfectly then. After replacing the ignition coil, camshaft sensor and crankshaft sensor, it is still hiccuping a bit - just a brief hesitation a couple of times a day but enough to keep me off the interstate as I'm expecting it to stall out at any time. After reviewing all the electrical quirks it has, I'm thinking it may be a short in the wiring or a poor connection somewhere. I started writing them down and realized - jeez this thing is screwed : )
The horn works sometimes. Maybe on the first try a bit but not the second.
I have to jiggle one of the connectors on the steering column to get my dash to light up after fiddling a bit with the dimmer switch.
I got some codes indicating MAF, O2, and vehicle speed sensor were faulty but none were the problem as I discovered after replacing them.
The speakers sometime buzz and sputter a bit when the stereo is on - like just randomly and then they're fine.
The rear drivers side tail light sometimes doesn't work. It's been a while but sometimes.
The ROOM fuse burned out on me once. I replaced it. Seems ok.
The tachometer used to cut out randomly. It's been a while since that happened.
The dimmer switch - wow that thing, I have to jiggle it constantly to get the dash lights on at night. I tried switching it with another salvaged one and had the same problem. Maybe I'll try that one again.
The left front speaker doesn't work.
The drivers side front passenger window button puts the window down but not back up again. Same for the rear passenger window.
The defroster doesn't work.

Obviously I have few requirements for the vehicle that I drive - but driving it is one. I can live with that other stuff. So I've cleaned up most if not all of the grounds and today went through most of the engine connectors and tried spraying some automotive electrical connector cleaner in them. I realize that's a long shot and maybe anathema to some folks, but I don't have much to lose at this point. I'm going to recheck the grounds tomorrow. And maybe look for some connectors down low or beneath the car that may have gotten oil on them. I don't know if I can justify taking her in for a pro diagnosis.

Thanks again for your input. I'm trying to get as much info as possible so I appreciate it.

Also, it's a manual transmission.
