I know this isnt a trailblazer forum, But I need some help. My wifes trailblazers Check engine light came on and then the low engine power light came on. Anything I should look at that might have caused this. Oil pressure guage reads fine. Any help would be greatly appreciated.

Update, This morning, I disconnected the battery for about 30 minutes. When I reconnected and started it, no SES light or Low engine power light and it runs fine. Any idea on what may have caused this?? Thanks in advance!!

Next time it happens get the codes read. Otherwise it's anybody's guess.
