  post locked   Engine hesitates on acceleration  

When i press pedal slowly, it goes a bit better on acceleration, but if i press the gas pedal harder it hesitates and sound from exhaust is like bruup bruup bruup and the car just cant accelerate and i feel like engine gets load and i feel engine drowns with fuel and cant ignite and a bit smell coming.

On the other hand, i try to remove the throttle position sensor when i start the car and nothing changed when i remove it, is it throttle sensor ? thank you

I'd be looking at the simplest things first .. Worn plugs (gap too large), clogged fuel filter, etc.

Diagnosis should be a process .. attempting a premature conclusion can take you down a rabbit hole that's hard to mentally back out of.

Heck, even engine vacuum hoses .. you'd be surprised how many driveability issues I've ghosted over the years discovering the last half inch of a vac line had cracked with age.

Did the issue suddenly come on, or has it been getting worse with time?
