When I step on the gas my car sputters or jerks and its hard to speed up.
I recently changed the air filter, fuel filter, tune up, and I add fuel injector cleaner when I fill up. The problem still exists. I just had the tune up today and driving back home it did it again. What do you think? Thanks.

You need a fuel pressure tester and hook it up to the fuel test port
