Hello I need some help trying to fix my truck it's a 2005 Silverado 1500 Z71 with a 5.3 with 205,000 kms the truck is in spotless shape but for some reason last week it just stalled out on me, now when the truck gets up to normal operating temp. I got about 10mins then it spits and stumbles then stalls out on me, but if I wait awhile it seems to cool down and I can go a little further, I've replaced the fuel pump, maf sensor, crank and cam sensor and it's still doing it I could really use some help on this one

 

Is the check engine light on, have any trouble codes?

 

No there has been any lights on, and I've checked it multiple times even while running to see if anything would show up but nothing

 

I would do the PCV and thermostat next. Shouldn't cost you much. These are things I replace on every vehicle as soon as I buy it

 

Alright I'll get the parts and I'll see what happens thanks

 

Still no go, still having the same troubles
