Well, I waited. But no more. Part is packaged and going out tomorrow.

Interesting stuff. Remember the list I posted of memcal measurements? Double checked and V8 TBI and some PFI V6 also measure same voltage as four cyl TBI. Not sure why on the V6 but they do.

Back in GM school days, GM books and instructors said "2.8 V6 pfi fires injector every other reference pulse." Years later I said this and Robert said "Ummm... not here on my bench." ??? Maybe both were true, just different configurations for different ecm's. All I know for certain is this: The more I know about this the less I understand.
