[CraigO]

Idle:
RMMMMMMMM*CUTOUT*MMMMMMMMMMMMMMMMMMMMMMMMMMMM
MMMMMMMMMMMMMMM*CUTOUT*MMMMMMMMMMMMMMMMMMMMM
Never quits, just entirely drops out

Partial throttle:
Hesitation, and the exhaust 'fart'

Full throttle:
Hesitation throughout the range until about 5k where it evens out.

What is on the PT:

2003 PT Dream Cruiser (Turbo)
Stage 1
Straigh thru muffler
19,000 miles
Plugs installed 3k ago

This is really bugging me [xx(] - I'd like to hear what this may be before the trip to the dealer. Still under warranty until May.

Help?!
