Issues with throttlebody? ~ actual throttle position

chitownf4st · 08-14-2014, 10:30 AM

Hi...

I am wondering if one of you has any suggestions on this topic. I am not quite sure why but my throttle does not appear to open up more then 80%. I tested this using INPA and throttle does not open any more then 80%... do I need a new throttle body? I also verified this is the case monitoring the live feed on the openflash tablet.

Could there be a kink the the vacuum line or is there a pump that controls this operation?

Do you have a piggyback? I had this problem once and it turned out to be a loose pin in the piggy's wiring harness

Pedal position should read 99 at wide open throttle, and TPS actual maxes out at 80-81. What you're seeing is normal if you're looking at the throttle position actual value.

80% is actually 100% on OFT.
