Weird thing happened with my car recently. Noticed it like 3 weeks ago. Was driving and had a full tank of gas and 2 other people in the car and it felt like every time I tried to accelerate something was holding the car back from going faster. What it felt like was I'd hit the gas, whether it be hard or normal, and it was just lugging to get up to speed. Didn't pay much attention to it since the car was packed and had a full tank of gas. But. I was driving it today and it was fine, driving it home after shutting the car off a bunch of times (running errands), it felt the same. I had an injector replaced like 3 months ago because the car was running funny. Anyone know what I should check into?
