My 2006 sale envoy with start up and run at idling for 15 minutes then it will cut off.But it will start right back up..if u keep giving it gas in neutral it will stay running
SOURCE: car runs rough at idle
clean out ur throttle body, just follow the hose from the air filter to the throttle body. Need 2 people to do this. Don't remove the hose completely from the throttle body. Just enuff to be able to spray ur intake cleaner into the throttle body. Do this especially if its worse when the motor is hot, as this would confirm the problem.

I am having the exact same problem. Did you get it running
dude your electronic ignition system has gone bust... you will have to replace the engine mapping chip, but good luck finding it... I tried to no avail.
Tell me if you get it though.. Goodluck :)
SOURCE: 2006 Envoy stalling when idels and won't stay running
Clean your Throttle body and pay attention to the Idle Air Control (IAC) valve passageway to try to clean the IAC. A dirty or faulty IAC will cause your engine to stall at idle, the job of the IAC is to open the passage way through the throttle body to regulate the amount of air to enter the engine to keep it from stalling when the Envoy is at idle.
Start with the simple and clean the throttle body and inspect any loose or damaged wire leads to the throttle body. Replace or repair any signs of damage.
Thank you for using Fixya and good luck.

P1345 "Camshaft To Crankshaft Position Correlation Fault"
Maybe a sensor ( camshaft or crankshaft position) is failing or has a bad connection at the plug.
Check both the camshaft and crankshaft sensors:--
The camshaft Position sensor (CMP) Is located on the front of head, directly above the belt. Small bolt holds it in, and it is a round sensor. If any belt maintance was done recently, Look for the sensor to have been damaged. It is the electrical connector that is EASILY damaged by a ratchet when turning the belt tensioner to remove belt.
camshaft position sensor, Don't forget to remove and clean the camshaft position solenoid.
908 is the sensor 421 is the Solonoid. click on the link directly :-- http://www.compnine.com/largeimg/060425TS00-402.gif
The one on the front of the block is easy to replace and the cam position sensor actuator solenoid is on the side. To replace the one on the side, where you may also find oil in the electrical connector, the serpentine belt must come off and the power streering pump must be loosened by inserting a socket through the holes in the pulley where there are three bolts.
----------
The crank sensor is located on the drivers side rear of engine just below the starter.
Check both this sensors.clean the sensors and refit it and check.If still the same error code 1345 then its either the faulty sensor or timing issue.The timing belt needs to be rechecked.
Also the camshaft position sensor code may have set because of the low oil pressure to the variable timing system from low oil in the motor.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

- The pcm detects that the camshaft position is out of phase with the crankshaft position
