New build truck stock 94 k2500 350
got it on the road friday after 1 year build ran ok no problems, went to move sat morning high idle 1100 .
swapped iac tps and map no change other than better baro reading.
so I fired up tunerpro and every thing looks good other than code 44 o2 lean/ 34 map low/42 ignition error
cleared them after new map swap and no codes no improvement im out of ideas . no obvious vacuum leaks . help i can provide any sensor data or logs thanks
