Leaky injector(s)..?? (bad idle, etc..)
Vette sat since Monday until this afternoon... because of the snow and ice.
Anyway... start it up... and it idles REALLY bad ... i give it gas to say alive and at 2k rpm it sounds like 400. 10-15 seconds later... instantly it's better and idling at 800-1000 like a normal cold start up.
I got out after it fixed it self and there was gas smell out of the exhaust.. very strong.
Also, to note, the coolant/oil temps were 45degrees. The computer puts more gas in the engine for start up.. and I believe the computer is told to put even more gas in for very cold starts.. right?
Sound like leaky injectors to anyone else??

Often a leaking injector will be noticed after it has been shut off for say an hour or so. Try this and hold down whe accelerator about 30 sec before trying to start up, maybe a minute in very cold weather. This will allow accumulated fuel to evaporate some and make starting easier.
The above was recommended as a decent test for leaking injectors.

Ok, pressure started at 45psi.. 30 minutes later it's down to 20psi.. what should I do first? Check the plugs to see which is wet? Scorp said to check the pump and the pressure regulator.. pump sounds fine. no clue how to check the pressure regulator (only thing it could be is leaky right?)

Yeah, LT1/4 fuel rail is easy to work on. I'm still really questioning why it instantly fixed it self after 10-15 seconds though.
Obviouslys, after checking fuel pressure, something is leaking though.
