OK got the OBD2 port hooked up and working right. The code it is showing comes up to PO1022. I changed the TPS didn't help. Truck Idles great. but if you try to get into it it still bogs. this engine and computer was DBW now I am using a DBC Throttle body and the computer has been tuned. the exhaust is down pipes and cats. stops right next to the transmission, could it be lack of back pressure or loss of when u throttle up fast?
