Vehicle just recently started hesitating under hard acceleration, and is very bad especially from a stop, it sometimes is so bad where the vehicle feels as if it wanted to stall, I recently cleaned the mass air flow sensor and also got a new air filter and also cleaned the throttle body. I did try and research the issue and came across the EGR valve which I did notice on my vehicle is very old and rusted. I was driving the vehicle today and was cruising and tried to accelerate hard and the car seemed confused on what to do , or how much air it needed , and also when trying to accelerate hard you could hear like a thumping sound , not really sure where it came from but this issue is very annoying and i would love to be helped and get this issue resolved, and the vehicle starts fine and idles okay , I wouldn't really say it has a rough idle. And the vehicle also hesitstes when pressing on the gas pedal while car is idling in park
