Shutting off 2006 trailblazer has been shutting off when coming to a stop and slowing down to turn the engine light is on when this happens

SOURCE: 2006 trailblazer po 411 code check engine light comes on and off over time is it a sensor or the air pump?

Check all your vacume lines one may have a crack in it

SOURCE: just bought a 2006 chevy trailblazer. the engine

I suppose the engine code said that cylinder was not firing or faulty? I would immediately get a compression check done on the engine. It is relatively painless. My burnt valves (compression 10psi vs 150psi) could not be diagnosed any other way. Does this help?

ok well try this when it stalls see if spark is present and if it is not and it cools down and starts then you might need to replace ignition control module good luck

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

The VVT (variable Valve Timing) solenoid may be dirty and will need to be cleaned or replaced. Poor maintenance (lack of oil change) will cause carbon and sludge to accumulate on the VVT screen causing the VVT to stick which will cause the issues your experiencing.
You may get lucky by trying to clean the VVT by adding a can of Seafoam to your engine oil and running it in there for the next 250 miles and then giving the Trailblazer oil and filter service with the recommended 5W-30 weight oil, anything heavier may cause the VVT not to function correctly as it is now.
Start with the simple and add Seafoam (Auto Zone, Part Source) carries the product. Service the engine oil after 250 miles, and at worst you may have to replace the VVT solenoid which is simple to do. Keep me posted if you have to replace the VVT.
Thank you for using fixya and be safe
