Having a problem with a chevy truck. Thought you guys might have some insight.

Truck is a 2000 chevy 5.3. It runs pretty well until it gets warm. Then at low idle, it dies or tries to die.

Replaced fuel filter. Going to clean the maf sensor tonight when I get home.

Ideas?

Clean the throttle body and maybe the maf sensor, check for intake leaks.

Make sure the plugs look good and are gapped right. Plug wires look ok?

Vacuum leak would be my guess. Take a propane torch (unlit) and go around the fittings and parts. If you hear the engine change (sucking some propane into the engine), you found your leak.

That was going to be my next move.

That and cleaning the maf and throttle body.

But I was successful in guilting my mechanic’s shop into working with he truck in today, so I turned it over to them.

Below zero here and only getting colder. Sooner I can get this truck back into the stable and running the better off I am. Don’t want to have to fire up the diesel pickups just to run around in if I can help it.

Got the truck into the shop.

Leak somewhere in the intake. So they ordered intake gaskets and oil pressure sensor and knock sensors. Just going to have them do the work and hopefully get it done by tomorrow.

I did. Only thing that showed was a O2 sensor. Replaced that.

Ended up with new intake gaskets and replaced the knock sensors and oil pressure sensor while it was all apart.

It is done to the tune of ~$900

That's not a terrible price given what you had done.

If you don't have a spacious and warm spot with all the tools you might need as well as being able to leave things disassembled should you get interrupted by "life", then $900 is a bargain.

Had the work done. Ran really well but started having problems again. Now more of a true dying at low idle, not just rpms dropping.

Took back in. They suspect either knock sensors didn't get plugged all the way in or defective new knock sensors

I know I'm way late to this, but I once had that symptom on a 2000 5.3, & the mechanic replaced the fuel pressure regulator. It ran fine thereafter.

OP - any update since 3/5?

Nothing like throwing parts at a problem when you don't know wth it is. Too bad, most shops are incompetent.. Hopefully you get it figured out.
