Car starts up fine as soon as I press the gas pedal it bogs down and does not want to go past 2000 RPM's and almost shuts off. Crankshaft position sensor, throttle position sensor?

Good morning.

I would check the fuel pressure first. Low fuel pressure would cause this issue.

Check the catalytic converter. A clogged catalytic converter will also cause this issue.

I would start with these two items first.

No to the TPS and crank sensor.

Are there any codes?
