Default 2015 Sierra issues. Experts or smartasses welcome.
2015 Sierra Denali 120006 miles. I bought this used and occasionally I would get a P0307 code. I'd erase it and it would drive for months with no issue. Last night I went to dinner..' all good. I start the truck to leave and as I pull out I get a stabilitrak light and a flashing CEL. Reduced power and bad idle.



Today I:

Disconnected the battery for a couple hours hoping for a miracle "reset" no luck.

Swapped 1 and 7 coil, plug, and wire. No luck



Observations:

NO lifter tapping

#7 plug was oily

When no code is present, oil pressure is about 30.

When stabilitrak light comes on, oil pressure increases to just over 40 and I can hear some sort of sound like air flowing or vacuum or something.

When I clear the code, the sound goes away and the oil pressure goes back to 30.

CEL comes on long after the Stabilitrak has been on a while. (minute or more)

Only ONCE after I first swapped the plug, coil and wire, I got a cold rough idle code P050D

V4/AFM does not engage.

My jeep is throwing a thermostat code. I bought the OEM part from Rock Auto along with the sensor and 4 things of anti-freeze, and will have my mechanics fix it on Thursday.
This is after I changed a right rear speed sensor.
That should darken the dash.

Edit: Too bad Gene didn't live closer. I'd have him do it.

How about a 2008 TrailBlazer SS with only 24K on it?

Turned out to be a bad fuel injector. Whew. Expensive fix BUT at least the heads don't have to come off. That had me nervous.

So what exactly needs to be done to fix this? No smartass, just wondering...

Pull the intake
Pull the fuel rail (under the intake)
Remove all the injectors and replace with new
Replace the rail
Replace the intake.

I most likely could have done it, but this work has a 30,000 mile, 3 year warranty parts AND labor. Let them have their fun with it.

Yeah, works great, but I only use it for RED idiot lights. CEL is a dull yellow and doesn't need tape.

The deactivation device for AFM has a bright BLUE LED but it's down by the pedals and helps locate things dropped on the floor. Also not distracting enough to need tape.

While that is true, there is no denying that the fact that this one still has good lifters, makes it a unicorn.

If you had a Ford Escort there are services available that only work on that car model.
