I have a 2004 Chevy Trailblazer that is acting up. About a month ago, every time I started it upthe clock would be reset like the battery has died but no other symptoms; after 2 weeks of that, it magically stopped and everything seemed normal. A week later I started getting low idle RPMs and it even dropped low enough to stall. Felt like bad gas, so i did a full tank of high quality has and a fuel system cleaner. Now check engine light is on, RPM issue continues off and on. Ideas?

 

In my 2007 trail blazer out of the blue I had the check engine light with the down arrow in it came on speed dropped to 15 mph I stopped disconnected the battery reconnected it runs fine but has
a check engine light on now went to AutoZone they scanned it and asked me if it had been towed there was an error related to stability control?????
does any of this sound like what happened to you?

 

BTW mine is a 2007 and after disconnecting the battery it has never misfired or anything just has the check engine light on
