from a stop, i would accelerate then the hesitation would start around 2k rpms. it hesitates and stumbles if i give 50%? throttle around 2k rpms. I have to let go of the gas and gas again and it goes away. If I bring it up nice and smooth, and then give it gas, this problem doesn't occur. Car still checks a 55 ecu code some im not sure whats wrong. This doesnt happen everytime I gas the car but it gets annoying when it happens and im not sure when the next time its going to happen..
I read the symptoms might be bad TPS sensor, or a fuel pump thats going bad.
I have fresh spark plugs in my car and 15 degrees from my NA.
