Hello,
Year of vehicle 2006
Make of vehicle Chevrolet
Model of vehicle Trailblazer
Engine size 4.2
4WD LT
The truck will loose voltage when in park with nothing on but the AC if i put the radio or the lights on it will stall out completely. Had the door open the other day for maybe five minuets, i walked out ten minuets later and it would not start. I brought it to AutoZone and they told me the battery was 100% charged and pulling 14 amps but that the battery was bad. after a quick jump (quick meaning putting the cables on another running car and then starting it and it will run fine. have a couple codes
P0223
P0506
P0222
P0122
P0014

Four of those codes are pointing towards the TAC system. Three of those codes( p0222,p0122, and p0223) can cause the engine controller to turn on the reduced power message and even turn off the engine. P0506 means the idle speed is too low. P0014 has to do with the exhaust camshaft position phaser. I have seen the p0014 pop up when the oil control valve solenoid for the camshaft phaser goes bad.
The first thing that you should do is make sure that your charging system voltage is good.
Then clean the throttle body. When you clean the throttle body, make sure that the throttle opens and closes smoothly with your fingers. If the throttle is gummed up or the bore is dirty, stalling and hesitation can occur if the battery is disconnected and reconnected.
Once the throttle bore and plate is clean, clear the codes and see which ones come back.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I also noticed that the engine seemed very hot for the time i was driving. Could this be related to lack of oil flow? Also, where could I buy the oil control valve solenoid?
