I'm running a bigger intake manifold and bigger aftermarket throttle body which doen't have the intake air control valve fitted on the bottem.
I had to do acustom job to fit the oem TPS.
Problem is....
Car won't idle on cold start until engine is warmed up.can won't rev smoothly pass 2k rpm.
At 2k rpm it will start hunting. If TPS is disconnected it will rev smooth over 2k rpm.
using a standard Ecu to run in the engine.
How did you guys with bigger throttle body solve this problem ?
