OK, Bought a 07 with a couple problems today.

This will help you fix the P0011. Don is correct that it's normally an extremely reliable system.

Sluggish oil pressure gauge and 15psi at hot idle are both normal.

Thanks. I have already watched that video.

Here is a video that might be worth trying if the sender and screen is good

Nice looking ride.

While nice looking yard of many toys.

Not really.

Is it normal at hot idle for throttle to show 21% ?

What ACDelco spark plug has the proper length for the 6.2l engine?

Length? Or do I you mean gap?

 

[SpareParts]

Thanks.
Length. Looks like .689
They also list one that has a length of .7xx So that's why i was questioning what the proper length was.

I think i have a plan for the oil pressure and rough idle. Seems like a good plan anyway.

This weekend.
Change sender and check for screen.
New Plugs, wires.
New intake gaskets.
New valley cover gaskets.

If that does not fix it then the next weekend will be,
New oil pump. Milling 10355HV. Maybe new VVT stuff. Its not that much and im in there already so.

If that does not fix it i will have to assume the motor has bad bearings and will replace the engine with a 60day warranty wrecking yard special.

Don't forget about the o- ring on the oil pickup tube in the oil pan. Notorious for going bad and causing low oil pressure. As far as I know oil pumps rarely fail.
