I caught the hesitation while datalogging. This is a warm start, the car had been sitting for maybe 40 minutes before logging this. Started, fuel trims are at a staggering +60 (60% lean). Then the idle drops (which the datalog didn't seem to capture because the tach dropped to like 400 RPM), engine starts choking out and the fuel trims drop all the way to -24 rich while its acting like its going to die. NOT PICTURED: It'll recover, the idle will jump up to 1,200 RPM and both Banks skyrocket back up to 30-40%. This is after Brisk Racing Plugs and a new MAF installed this morning.
