Gt500 throttle body idle issues

[etp2828]

Does anybody with the vmp gt500 throttle body have issues keeping the idle around 750-800rpm?

No - you need to check the TPS voltage, make sure the blades on the TB fully close, check the IAC valve, or check for vacuum leaks. Likely your culprit.

I'll have to look for vacuum leaks. IAC is good. I adjusted the blade slightly. I'll make sure its closed when I check it again. Appreciate the input.

Should probably add it's a bit of a frankenstein set up.

And my blade isn't closed all the way and my engine idles at 750rpm. A slightly open blade lowers the IAC duty cycle.

Has anybody had dealings with the throttle body not having an opening for the IAC valve? If so what did yall do to fix it? Sent from my SM-G998U using Tapatalk

Yeah it does. I was close to my max duty cycle. When I got it the blade was slightly open.
