After a computer change everything needs to be checked out now! start again`, begin by checking the PCM computer is it exactly the same code number as the unit removed, Check with the company where you purchased it, was it bench programed before installing it! If this is not correct you can waste a lot of time.

Yeah but the computer I got was from a salvage yard but my old computer is good the the other one is not
