I went to pick the car up on 9/16/12-car would not start -he stated it ran fine but he claimed there were month old stored codes re: throttle body issues. While waiting for him to figure out what to do I tried the top .It worked fine going down. But would not close fully. Latch directly behind roll bar leaked.
Mechanic still has car to get it right. Keeping fingers crossed.

I had another cylinder leak just as I replaced one cylinder (seecond and third leaker). At that point I decided ALL cylinders would be rebuilt by Dennis Ficken. Considering the labor overlap, I suggest you do the same.

The codes suggest you have underhood wiring issues that all 94-95 models have, and this should be next on your list.

mine is a 1993 ce cabriolet . Are they prone to the same wiring issues?

There is a good chance that it is. The problem spilled over to 93 and 96 models.

You can check your own vehicle by removing some of the loom from the wire bundles under the hood and look for disintegrating insulation. It should present itself rather readily. It's either horribly bad or it isn't. In your case, the immediate concern is the throttle body wiring bundle.

This problem gets worse the more you poke around under the hood. The insulation flakes off like glass under the slightest movement.
