Actually you could try this first.here is a bulletin.this is a common problem.Subject: Engine Stalls When Air Conditioning Is Turned On at Idle

Engine may stall with the air-conditioner on and or while adding additional loads to the engine at idle. An example of an addition load would be turning the steering wheel left or right with the air-conditioning on. This type of stall usually occurs during idle or slow parking lot maneuvers. This concern may not set any diagnostic trouble codes.

https://www.2carpros.com/articles/throttle-actuator-service

Clean the throttle body bore and the throttle valve plate using a clean shop towel with GM top engine cleaner, GM P/N 1052626 (Canadian P/N 993026) or AC-Delco Carburetor Tune-Up Conditioner, P/N X66-P, or an equivalent product.

this might help.

Hello,

It sounds like you have a vacuum leak or a mass air flow sensor that has gone bad. Is there any codes?
Here are a few guides that will help you get the problem fixed.

Today my car cut off when I pressed on the brakes but allowed me to cut it back on and it did the same thing. One mechanic told me it could be my fuel pump because my gas hand also doesn't work correctly. What do you think?

The only way you are going to know is to monitor a fuel pressure gauge while the problem occurs.

I was driving down the interstate after about 6 or 7 miles I couldn't get up to speed. Then the car started to sputter and wouldn't shift properly. Eventually I couldn't get the car past 50 miles an hour. The car idols fine and starts. It is not leaking anything. It ran fine in the morning going down the interstate shifted fine and ran perfectly normal. The day before it kind of did the same thing as this specific time. It was around 100 degrees out at the time. Could this be vapor lock or maybe a fuel pump or fuel filter?

While driving on the freeway, all the lights on the dash came on at once and the car shut off. It isnt the battery. Any Ideas?

Engine Performance problem
2005 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 90,000 miles

I have a 2005 Chevy Trailblazer and over the last month or so I have had problem with it stalling when I am backing up out of the driveway or parking spaces. This does not happen very often, probably about 5 times in the last 6 weeks but it is not something that I can pinpoint to a particular action other than backing out of somehwere. I really dont have any warning that it is about to stall but the Trailblazer idle does seem to be lower than it had been in the past. I am not sure if I should be looking at an electrical problem or a tranmission problem. There are no indicator lights on, it just stalls and then starts right back up with no problems. I also do not hear any noises when it stalls or when I start it back up. I am totally confused. Please help

It keeps shutting off while driving. It's not battery or alternator. What could it be?

Once it cuts off, what do you have to do to get it going again? Is there fuel present at the injectors when it cuts off? (I know this is a little involved, but these are some general questions which come to mind). Hopefully we can continue to communicate until we've narrowed it down significantly. And eventually cured!

Engine Performance problem
2005 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 39000 miles

Hello, my 2005 chevy trailblazer has recently started to act up when driving it. Although, it does not happen all the time. Sometimes when you start from a stop, it will act as if it wants to die. For example, starting from a red light, pushing the gas pedal, it acts like it wants to die, but only for a sceond and then it goes back to normal. Also, when I made a turn, slowing down for the turn and then pushing the gas pedal down to make the turn, it acted the same way like it wanted to die. Does this sound like the fuel injectors need a real good cleaning, maybe replace the fuel filter and/or clean the throttle body? Does the O2 sensor have anything to do with this type of behavior? Or is it a totally different type of problem? I asked the same question to the just answer website and they were zero help, so please forgive me if I do not donate immediatley. Thanks.

Joe f.

Possibilites are numerous the best way to find out is to have truck hooked up to a diagnostic scanner and check all the computer controled devices. Your symptoms do not give enough info for any definate repair.
