I recently purchased a 93 ls with a bad trans I had a used trans put in and was planing to sell the car after I got it running. the car run but sometime will shut of with out any worning its hard to start after it kills you have to give it gas and once it starts the rpm will flutter and then it will die again.

The car was sitting at my friends house out side since thanks giving or so never ran or touched my question is could the gas cause the car to have this problem if not could you help me out I would really appreciate it.

 

Could some one please help

also forgot to let u know it is auto if that makes any diffrence.

 

depending on how old the gas is yes gas can be the problem or it could be many other things....how long has it been sitting?

 

About 5 or 6 months with 3/4 of a tank it was also really cold and had a lot of snow around it if that makes a difference. I'm guessing that the fuel filter is going to need to be replaced not sure if the pump will need to be
hope not don't have a lot of $ and i need to sell soon.

 

my advice would be do a full tune up to prolong the life of the car for the next buyer and keep receipts if you want to charge them more...
do fuel filter, then run seafoam without o2 sensor in header...
then change spark plugs, wires, cap and rotor, and oil change...
should run like a beaut when done if you use fresh gas before all of this

 

Thanks for the help i will probably do that once i get all the cash.

 

You can try adding a bottle of that Heat Water remover which has a lot of alcohol or methanol which removes water from the gas.
