I have an 04 Trailblazer and I had the same problem.. I had to have the battery replaced and it started doing that.. We figured out the problem an 04 doesnt have a memory saver on the battery so the cheap way to fix it is to take the throttle body off and clean it. Because it has no memory saver when we took the battery off it made the car think it was brand new. a memory saver is like $100.. But ever since we cleaned the throttle body we havent had any other problems.. We got this information from a dealership..

The memory savers I've seen are little 9 volt battery gizmos that plug into a powerport. Haven't looked lately but I remember seeing them for around $15 and up. Good mechanics use them so you won't lose your computer settings or radio settings when the battery is disconnected for whatever reason.

I have to clean and tighten the battery terminals often. I keep a wrench in the car for just that reason.

I have a 2002 trailblazer and it has had a similar problem for years and no one has been able to solve it. tkazee, did you ever figure this out? My car starts fine when it's cold and fine just after it was shut off. But if the engine is hot and you stop for 10-15 minutes, it acts flooded and won't start. Then I must wait until the engine is cool and it starts. If I can get it started when it acts flooded it will sputter and miss for a bit (as if flooded) until it finally runs right. Anyone have the answer?
#120 of 124 Air conditioniong during idle car stalls out

Air conditioning works well but when slowing down to a stop at idle, it will stall out or idle up and down and try to stall out is this a vaccum or a carbon build up problem?

My 2002 trailblazer died while driving and now the engine won't roll over. My starter relay will not kick in but the relay is good and I bypassed the relay with the ignition switch in the run position and rolled the engine over but no fuel or fire, and yes the ignition switch is good. Is it the PCM?

Did you ever get your problem fixed or did it go over the cliff...?
I have a 2004 80k that is developing a rough idle.. just changed the air filter and want to change the oil and include some ProLong.. I use in my C-cars.
Just wondering where we are headed here...

We did not solve the Trailblazer problem. We did learn that the compression is a little low, but the wet test compression is normal, so the loss seems to be in the pistons. However, it does not use much oil. I have been adding Marvel Miracle Oil to the gas and it runs better. My solution for now is to keep driving it.
This car also seems to have a history of a vacuum leak at the top of the gas tank. We replaced all those parts, but the rough idle did not go away.

take the throttle body off and clean it, took care of my same problem, I would pull up to a stop light and the engine would die. Now it runs great. 180,000
