I installed a HHP 105mm throttle body on a ported snout . The car starts and drives fine but as soon as you come to a stop I get the throttle body symbol and a check engine light (P2118) but as soon as I press the accelerator pedal the throttle body symbol goes away and the car drives fine till I come to a stop . it happens around 20 mph or less. any ideas? (all throttle body tables are stock )
