2017. pump should be okay no problems at full throttle or anywhere more than idle. Im beginning to think its somewhere on connectors or cables the main problem. I drove it yesterday and at some stops the idle was fine, but rpms still not going right down when applying throttle. o
Is your TPS working? IAC working? Bad injector?

TPS shuld work coz if i turn him without reset then he idles higher about 1600rpm. IAC or ISC if i get him out he moves out end in so it shuld work also. MAP sensor shuld also work properly he gives reading when conected to multimeter.

also injectors should work properly i had them out and start the engine it sprayed fine… i think

today i had a bit hard ride. The red light comes on when presing hard throtle and stays up until you turn the engine off. After start the red light is gone till again hard throttle.
Ebay ??? New they are $650

im leaning towards the map sensor. The book says it shuld be 2,5v at idle. Mine is 1.3-1.4. And 2.77v at key turned on. culd anyone check their map sensor readings, that i dont buy a part which is persumambly faulty.

the sensor part number is 0430-072 lots of machines have the same sensor.
