Most likely cause is the TPS (Throttle Position Sensor) which regulates your idle speeds for cold,warm, and AC operation. Some TPS can be adjusted (would have a set screw) but not in all models. If your TPS is not adjustable, it will need to be replaced.

Fault code P2106

is it the ecotec engine fitted 1.8 or 2.0./2.2l or the diesel 1.7 engine.. how long have you not used the air con for. not using it for a long time you can damage the pump the flown sensor. even the temperature sensor. but if the engine is trying to stall with the ac on then the pump may have a fault. ac should be run for 10min once a week no matter the weather. stops you having problems later.

I have a 1997 Bravada heat doesn't work new radiator, new water pump, new thermostat what else could be the issue for the heat not working still.

maybe the tap for allowing the water into the heater rad is not opening or the heater rad is blocked check the two hoses coming from the heater rad and see if they both feel the same heat when the engine is hot

1993 GMC Suburban. When truck gets to 25mph it won't shift gears and gets sluggish. I have to continously tap the accelerator to get to quit ''acting sluggish'' but it won't go over 50 mph. It's also...

Inspect your TPS (throttle position sensor) and the wire leads. If wire leads seam to be good, replace the TPS.
If your have a 700R4 transmission, check your TV cable and adjust accordingly. But i believe your Suburban has the 4L60E and is electronically controlled.
Thank you for using Fixya and good luck. Simple and easy fix.

Sluggish and stalling

Could be many things but check the simple and cheap stuff first: fuel filter, air filter, O2 sensor, or spark plugs. If that's not it the more expensive problem would be: alternator, gas pump, or maybe even something with the transmission
