Hi I'm Abby, own a 1985 camaro 305 v8 backfires at high idle out of the carburetor and stalls after starting up. I'm only 19 don't no much about cars please help.

Abby,
Where you located? How many miles? If you have high humidity or generally wet weather, make sure the plug wires are seperated they could be cross arcing. Same with the distributor cap, it can develope arc trails inside, rotor to, even the plug wire ends. You could pull plug wires one at a time to see if the symptoms change. Delaying the distributor slightly could help. Make sure you mark it if you do not have a timing light. I would go counter clock wise no more than a quarter of an inch. Finially, suspect fuel pressure of being to low. Low pressure will lean out the engine as the engine consumes more fuel at higher RPMs.

Hi im ogre u may be in need of a tune up or ur getting to much fule
