gas and it goes but i can't give it a lot of gas or it

an hour and then started doing the same thing

is the check engine light on? Google "how to read gm obd1 codes" it is easy. also, it would be a good idea to test your fuel pressure. weak fuel pump could be a problem. if your pressure is out of spec for your engine it wont run right.

Backfiring is a timing issue.
