First off, beautiful car. Now to the dieseling. It's usaully caused by too much ignition timing. Do you know what it set to at idle?

I like it! Good find.

I think if you hold the third button it pops your trunk, but I'm no expert.

Hmm, I've gotta ask you guys if this is normal. Today I stalled in an intersection (first time I've stalled in 3 days of driving) so I acted casual, put the hazards on, put the clutch in again and made sure I was in first. However, when I went to turn the ignition it wouldn't click over. I immediately went into panic mode and tried until about the fourth time when it would turn over. Is this normal?

No. The only thing that pops into mind is a potentially faulty neutral safety switch. If it happens again, take it out of first, into neutral and back into first, pumping the clutch, and see what happens.

The swtich is designed to keep you from starting in gear. Jeeps (at least most Wranglers I know of) don't have them so you can start in gear.

Yeah, I've had this happen before after stalling, but usually it will turn right over. However, the rpm's would jump between 1500 and 500 and die in a couple seconds if I didn't gas it.

Started her up today and am still having a rough idle. However, I can now hear belts squealing at startup. Could these be related issues?

I'm not sure, but doubt it. Are the belts worn? Do they seem to have decent tread and tension? The squealing is coming from them slipping on the pulleys before they grab. It's worst when it's cold and the rubber is hard.

Your rough idle could be from a large number of things. How many miles? When (if ever) did it get a thorough tuneup? Fouled plugs and dead O2 sensors don't bode well for performance. A failing MAF certainly could effect your idle. Any thought you might have a leak around the intake?

I always think it's strange when people supercharge a 4 cyl. But still cool. If the car is idling the same as it was before you took the key out, it may have to do with the alarm, if it's not an intermittent problem. But if it's 'dieseling,' running rougher but still chugging along, it does not have to do with the alarm.

Your rough idle has nothing to do with your squeaky belts. Your throttle body/ IAC is probably just dirty. Spray a ton of carb cleaner in there, then get it up to operating temp and run it hard.

You could use my favorite SeaFoam too. It's kind of amazing how much better some cars run after it's been used. Just bring it in through a vacuum line to the intake for a bit. Let it sit a while, fire it up and observe the battleship smoke screen that may emit (if it was all carboned up in the cylinders). Good advice on the TB too.
