Re: Truck won't start right up and backfires like crazy!
It sounds a bit like an improperly adjusted choke solenoid. I would recommend looking at it when its cold (californias version) with the key in the run position and see if the choke is closing. Look at it first with key off (should be open) then turn key on (should close). Remember you should not be touching the gas peddle to start with the electronic choke. If the butterfly is closed with the key on have someone crank the engine over, does the butterfly shudder like it wants to open? How many turns are your mixture screws? Did you make your wires or buy them? Did you check resistance on them?
