OK so i took my car to Oriellys and read the code im getting right now its:

P0221 Throttle/Pedal Position Sensor/Switch B Circuit Range/Performance Problem

when i drive the car its fine then all of a sudden i get "eng power reduced" and i have no throttle response PERIOD. this happend to me on the damn highway! so i turn the car off and back on and it works fine for a few mins then boom, again.

I replaced the evap solenoid after research on here and it ran better for a few mins then boom no throttle again. so i reset the car for damn near 25 mins started it let it run 10-15 then drove and not 2 mins into the drive it did it again.

any ideas?

No

Maybe it's dirty and needs to be cleaned?

Eric, from researching, it looks like the only fix is a new throttle body.

The code book says: Throttle position, Sensor #2(redundant) range check poti voltage - Primary malfunction signal and criteria = sensor difference > 9(threshold value) specific units = %.
Secondary Parameters = battery voltage > 7 volts, continuous.

Will a simple cleaning fix that problem or do I need to just get a new one?

I can't find any how tos on cleaning

I personally don't know a "quick fix" for that so replacing it may be the only alternative.

This is also happening to me. Does your ESC turn off too?

You can't clean out the TB easily. Carb cleaner will kill it too. Did you spray something through the intake, like meth?
