I just got this car, half a tank of gas was in it, after sitting around for a year, i used about a quarter of it. then i added fuel injector/carborator cleaner. then i filled up the tank with new gas.
it started jerking on a short trip the other day and i noticed the brake, gas, and battery lights were on. then when i tried to start it the other day, it only ran for a few seconds and stopped. i replaced the fuel filter and some gas cleaner, which helped a little bit. now it runs for about a minutes and still jerks. would heet and octane booster help?
