When pushing the gas peddle for the first time...
My Mazda Protege 91' started to go-stop go-stop when I first hit the gas peddle. Once already moving - no problem. I also noticed that if I am stopped up-hill, the engine cuts off (won't remain idling) + if already in motion (while up-hill)-the back and forth motion won't stop, and it would fail to climb up-hill. I replace the fuel filter, spark plugs + cables and there's no difference for the better.
Is this a good question?
Thank you, everyone, for responding. It turned out to be a failing timing-belt. It eventually quit altogether. I'm now looking to see if the valves are bent or not. Either way - it's time for a new car... Thanks again.
