My car wants to stall when it's idling. Especially at a stop light. It stalled out almost completely until I put some antifreeze coolant, which was a little low but not empty. I am frustrated. Mechanic's Assistant: Has your car been overheating? Have you noticed any leaks? No overheating. Leaking yes Mechanic's Assistant: What is the make/model/year of your car? 2006 Chevy trailblazer Mechanic's Assistant: Are you fixing your TrailBlazer yourself? What have you tried so far? Not fixing. Haven't tried much. Mechanic can't figure it out Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I guess not

Good Afternoon, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you, so sorry to hear about the issues here on the Trailblazer. I know how frustrating it can be to deal with a stalling vehicle. Now just so im clear you started running better after the coolant was added? what has the mechanic tested and ruled out already?

I have been having this issue for approximately 3 months. the gauge goes down way under 14 and acts like it is going to stall. I always make sure fluids are in my [engine](/topics-engine-chevy/). coolant was a little low but not empty. had mass air flow sensor replaced. I have other errors coming up having to do with air..oxygen sensor etc .I believe bank 1The engine almost going to die. Made to gas station and topped off with coolant. Ran engine for 10 min

okay thank you, \*\*\*\*\* \*\*\*\*\* one thing that causes a stalling like this is due to a lack of air. i would advise that your mechanic inspect the throttle body to ensure its not excessively dirty or clogged up since if it was we would have this issue. If we has ruled out that the throttle body is clean and is opening correctly we can suspect a deeper engine or engine controls related issue with the idle but thats not very likely without any other symptoms or codes setting.

Ok. I will ask him to check. Seems to me I replaced that but will double check
Automotive Expert
okay sounds good!

Automotive Expert
no problem!

I replaced throttle body in 2019
Automotive Expert
ah okay, being over 2 years lets go ahead and get it inspected anyway like i mentioned

Automotive Expert

Automotive Expert
