Hello I am in the Marines and have put my Camaro (LT1 5.7L) car in
storage twice since being stationed overseas. I have trouble starting
it to to an idle (sporadic) but once it starts it runs like a top. It
does not happen all the time. Just put new plugs in it and I am a one
owner of this car. It will turn over then run then start running
choppy. Then when you restart it it runs perfectly fine. Any one have
an idea what might be causing that? I only run Shell Premium on this
thing or EXXON gas. Always 93 octane. I have run the gas down to
almost nothing and refilled it at another Shell Gas station. Dont
think its bad gas. Please help me anyone?

hello Derrick,

have had something similar with my V6. It was the generator. And depending
on the battery's loading level it could be like you write. Whats the voltage
level at the battery terminals on low rpm? (My gen. didnt load at low rpm)

Thanks for the heads up John. I will take a look at that issue. I
just put a new battery in it and it got plenty of Cold Cranking Amps.
Did not check the alternator yet. Did your car have an issue with
keying the ignition a couple of times then it fires right up? That is
what mine is doing. Runs fine when it starts. Thanks and take care.

looks like your ign switch shows either an high transfer resistance or
looses connection sometimes.

Try moving the starter key a little while engine runs properly (not while
driving!).

John I took it to MR Goodwrench's advice when I took it to the GMC
dealership. They troubleshot it and recommended a TPI Plate Cleaning
followed by a Fuel System cleaning as well. I took thier advice and
had them do it. They told me they could not get any cold start
problems, or any problems like I explained; but still recommended this
course of action based off my cars explainded behavior. Well that did
not fix it. The next morning it went back to the same old behavior.
So they told me (Chevy dealership) to bring it back and they would take
a look at it again. Problem is they keep wanting to charge for a
troublshoot. Not sure if I trust them. This looks like a try. If I
get any more issues I will record it then show them. Kind of wierd how
cars develope issues only at home not at the dealership. Thank you for
the heads up. I will give it a shot.

Take care
