you might also try jiggling the injectors while it is running...

look at you working the HPT now! LMAO

Man, it's gotta be a vacuum leak or something pre-o2. Unless your o2 is toast. Swap your o2's make sure the problem doesn't stay with the sensor.

i have been hooking up with him for the past month and this has got us stumped. and the 14.3 afr i had pe off from trying to troubleshoot this a while back. hell! at this point i wish it would blow.

i have sprayed all over the intake with a full can of supersized carb cleaner it did not move the trims a bit. so , how else do you detect the leak?
