Question about 2002 Chevrolet TrailBlazer
Check engine light is on. On my 2002 trailblazer. Also when air conditioner is on and ideling the engine wants to shut off.
I would think there is a problem with a sensor which my be an IAC Sensor. That makes the idle air control Hi or lo depending on what the motor is calling for. Have a shop take a computer reading and see what sensor is bad, As for the air There is a Air condition Amplifier and there may be a problem with that its not common but sounds like it may be the problem with your trailblazer. I sure hopes you out Flash68, If not get back to me and we can trouble shoot some more. Take care Bear001
