Hey guys,
I'm hoping you can help isolate a driveability issue for me.
For some time now, I've has this stumble right off idle as I'm just getting on the throttle. It only occurs while the motor is cold.
I've attached a log with two captured events.
This issue has persisted through tuning changes and different injectors.
MAF is a 399 model with honeycomb in place, and BOV is a stock crushed unit still configured to recirculate. I've checked for boost leaks up to 25psi and cannot find any. Throttle body has the FIAV block off but functional ISC. Trims are within 3% normally.
