I'm using ADX file $42-1227747-V5.ADX
I was using $42-1227747-V3T.ADX, I will try a later version and see how that works. I installed the new injectors but truck still runs lean. From a stop it just won't take any pedal. It backfires thru the throttle body several times then takes off only when held wide open. Gets a little better when fully warmed up. I have replaced CTS, IAC, TPS, MAP, both fuel pumps, tank switch and valve, plugs/wires/cap/rotor, injectors, made the fuel pressure regulator adjustable and cranked it all the way up. Fuel pressure checks 13psi on one tank/pump and 12 1/2psi on the other. it has a new air filter, oil filter, clean oil, fresh antifreeze, and all new vacuum hoses. The only things left are the O2 & EGR.
I need to get it smog tested to complete the registration process this month as all the fees are paid for last year, but the new year starts the end of April so I will be delinquent May 1. I'm worried if it fails smog they will label it as a gross polluter. I will drive it 50 miles to get it good and hot then take it in to the smog test shop tomorrow afternoon. I asked for a pre-test first, then, if it passes, take the official test immediately thereafter. I hope this works, 'cause I don't know what else to do.
