Hi Tom,
The starter is prone to get bitchy if you wash the engine. The drain hole is too small and gets plugged up under the plenum so just sponge bathe her. I had to R&R the starter to clean the contacts on my starter solenoid, but no problem since.

IF a Z backfires, it is almost guaranteed to blow off one end of the vacuum hose to the MAP sensor on the back side of the plenum. My stock one does it once in a great while, no biggie.

For all the electrical problems, the manuals are a life saver, the wiring is not as straight forward as old cars were. Grounds are everything on these cars as most all sensors and solenoids are energized by grounds supplied by the ECM instead of a good old straight shot of 12 v.

After reading the manuals many times over while working out small bugs, the terrifying thought of a 17 year old "rotten little Johnny type" splicing into wires to install an after market alarm system in a vette sends shivers up my spine.

I have one piece of advice for you, you might take it a little slower before making too many big changes, especially on electrical. Take a few long road trips before tearing into everything for all the latest mods. But then again.... it is easier said then done.
