The truck is throwing a Code 44.
The problem is not the O2 sensor or the pig tail.
The truck feels very lean, the new Cat looks like it was very hot.
It starts and idles great. Throttle tip in and it dies.
Both tanks are showing 11 psi, at idle and road test.
My GM service manual is kinda contradictory. Under "Fuel Control 4-3" it states 18 psi to the throttle body. Computer Command Control 3-29, Chart A-6, specifies 9 psi or above.
Any ideas?
