I am having idle issues and pulled codes and got a code 13.Can not control idle RPM during self test low RPM check in engine running mode.The TPS is new and the voltage is .092 volts and my idle is at 800 to 830 rpms when testing for codes.Then at times the idle will spike down to 600 as like the engine shuts down and fires up again?I unpluged the air by-pass solenoid and the idle drops to 600 and returns to 830 rpms when pluged in.I am thinking it's air by-pass valve either sticking or going bad.Any info would be helpful?
