I have a couple of issues for one the motor is out of a 2000 blazer. when i put the throttle it the floor it trys to stall out and i have a couple of codes. p0122,p1406, p500, and p1810. i under stand that the last 2 don't have anything to do with this. I have replaced the tps and cleaned the egr. Other than using a scan tool and checking voltage pulses is there anything else to check. It does fine as long as you don't put the throttle to the floor. Thanks.
