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?
