I briefly investigated a few of the vacuum hoses and intercooler lines in the engine bay and nothing seemed loose. Stock intake. I tried all three keys and the same result with all. Played with idle settings and timing on Cobb AP. Switched to Stage 1 map. Still no luck. Not sure how I'm going to do a proper vacuum test when the car only runs for 3 seconds at a time, so fuel pressure test may be next. I ordered an OBDII to USB cable and plan on using RomRaider to log parameters at startup. I also read about someone who had a similar problem and the AVCS solenoid was the culprit?
