@coryoncarsofficial: Where do I even start? This 2007 Trailblazer was scheduled for an intermittent stall at idle with a check engine light on. When I scanned it, it had about 700 codes and multiple issues. Let’s break it down into chunks and figure out where to start. #mechanics #CarTok #automotive #diagnostics #ChevyTrailblazer #checkenginelight #evap

Seems so simple, yet so complex for something so simple.

Having the same issue on a 07 Acadia. The VVT solenoid code comes back even after changing the oil, not sure what to do there, replace solenoid?

dad has a 02 envoy. saved it out of the scrap yard. rebuilt the front end, tire rods. wheel bearings, front axles seals, front and rear brakes, sway bar links X4. leaks fluids sure. but it runs great and it's 4x4 has never let us down yet. Inline 6 reliability. also working on a M52TUB28 bmw engine on the side. and a ford 300cui I6. too many projects 😅

The oil change lights on these cars can go upwards of 9000 miles. I have one of these, I change every 5k religiously. And my rear main seal leaks, so I also check every 500 miles.

Check the purge valve. also the MAF sensor will throw a camshaft sensor code too. These are common issues with the trailblazers

I have a P0171 code on my trailblazer. Any insight into what it could be? I can’t find the issue myself.

You guys are insane having the knowledge and experience to find small issues like this making big waves throughout the engine. My little garage mechanic self would've been so happy to find that old-
