Bsa,
I thought the same thing. Low idle has nothing to do with an intake leak. If there was an intake leak, you'd have a HIGH idle.
Gawd they charged him an insane amount of money for unessasary work.
I'd stop taking my vehicle to them.
From home:
check fuel pressure,
replace fuel filter,
replace fuel pump.
Clean mass air flow sensor.
Check condition/ color of spark plugs,
Check ignition system, clean connections.
Sometimes ignition coils or coil packs die intermittently only when engine heats up.cheap to replace.
Only use OEM stuff

Have you checked for any trouble codes? Would be the first thing I would look for. 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 OEM O2 sensor? Have you ran it after changing and deleting the codes, then checked the codes? Usually 02 sensor doesn't cause that much trouble, but sometimes aftermarket sensors are One Size Sorta Fits All. Buddy went through that with a Toyota. The sensors signal didn't exactly match OEM and wouldn't work. He paid the Toyota royalty and everything was OK.

maybe it's time we went back to simpler engines- you know; the ones you could tune to perform well without all the crap on them now.
Show class, have pride, and display character. If you do, winning will take care of itself.

Only use OEM stuff Initial problem was extreme high idling on startup, especially when cold. Intake gasket was leaking. Old school test showed that. The knock sensors ended up being a big chunk of the bill. And then after the first fix, find out there was a bad batch so they had to be replaced again. I can't remember what the book is on replacing an intake gasket on this engine. Maybe ~4. That alone is $500+. Truck runs perfectly now. Except throwing codes for knock sensors again.

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 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. Had a bad batch of knock sensors. Replaced them at no cost and truck runs good now. Except throwing knock sensor codes

Except throwing knock sensor codes I've got a buddy who has owned his own mechanics shop here in Helena for 10+ years. He says the quality of parts in the last few years has been total $hit. At least NAPA, CarQuest, and O'reilly's pay his warranty labor time when he has to pull everything apart for a crap part.

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. Yeah, that's an easy DIY project starting in June in Montana.
