Question about 2003 Chevrolet Suburban 1500
I removed the radio and heat/air controller on my 2003 suburban and now it will not idle correctly. Why?
Did you cap off the vacuum line for the heat/Air controller? Vacuum leaks will mess with your engine's sensors, particularly the Manifold Absolute Pressure Sensor, therefore messing up your mixture.

If you touched any of the A/C controls within 45 seconds of starting your Suburban (after the battery change), you messed up the 'calibration mode' of the HVAC.
Pull the HVAC fuse (10amp) under the hood, and pull the two adjacent fuses (30 and 10amp) under the dash listed as 'climate control' in the manual.
Push the fuses back in, restart your car, but DONT TOUCH ANY of the A/C controls for 90 seconds.
I bet the A/C starts working again normally.
