Since fitting the BBK TB i have had great gains in power BUT its changed the cold idle behviour dramatically what worked before doesnt work anymore.
What can i do to dial this in accurately again. It is simply starting and stalling - i need to push the throttle and keep the revs up well above 1200rpm or it will stall. After 30s or so it is OK.
If i check the AFRs what should i be aiming for at idle. I am not sure if the car has too much idle air or doesnt have enough??
Have been stuffing around for a few cold starts now trying to get it right.
The PLX wideband takes time to calibrate and settle - this is masking the ability to get accurate afrs. But i can plug it into an external power source and have it ready before the car is started. If this is the way to go.
