Cooter: Many thanks for all the input and the Tpieice link. Ill put the pressure test on the list. The fuel rail was flushed clean.
Only the the 1 large backfire through the exhaust so far with the others through the throttle body. I'll also try to upload a Video for you.
I'll try the carb cleaner as well as rechecking the grounds and then try the dongle when i get 1 and clear the codes.

Cheers Rod
