Drew said he's had a CEL since he's had the car...
Jeb has the wrong TB gasket one and thus a vacuum leak...
Steve's 'misfire' I'm figuring is a loose plug wire since I remember him and/or Pete fiddling with the wires. Which it seemed to run fine when I was there.
The sticking throttle cables though has me perplexed since it happened on both Drew and Steve's cars...
The other misc minor broken things are just, IMO, due to the cars never being apart. :-)
