DOH! You left us hanging - did it turn out to be valve buildup or injectors? Or did the dealer just shotgun it and do both so we'll never know?

Very good video, would you do some more common issues with this generation please? Myself use a good oil and catch can since new. Thanks for sharing. Cheers

Now that's good teaching 👍

2013 Chevy Silverado P2919A popped up, cleared it and ran some fuel injector cleaner. Hasn’t popped back up. Cannot find anything about this code

This is a common thing with GM vehicles from 2017.

Why not use a new coil & wire to check cylinders?

I have a 2017 Buick lacrosse and I’m getting a po50d

I have a 2014 gmc Yukon xl throwing a p219a code. How important is it to get this done? ASAP? or can it wait a while?

I have a 2015 Dodge Journey RT 3.6L, I have P219A, I have swapped Spark plugs, Fuel Injectors and Spark plug coil pack. When I replace injectors with aftermarket code goes away but I then get a P0172/P0175. Any help please.

Sparkplugs. The cold start is the sparkplugs. I did everything to fix my Kia soul and nothing . The last thing I did was the Sparkplugs. FIXED. No more cold start .

I got my car tuned recently after having headers installed and this code is still showing up..any tips?

Hey I just installed a new transfer case on my Chevy and now every time I step on the gas to hard my truck will go in like a neutral instead of grabbing the next gear and rev out anybody got some advice for me?

If i need my exhaust manifold replaced could that be whats wrong with the fuel trim ?

I have Chevrolet Sonic rs 1.4 turbo and I have rough start sound like misfires but I don’t have any codes even check with code reader

Oh my this guy is extremely handsome

Crappy gas

This is why KZfaq needs the thumbs down button displayed. You showed how to swap ignition parts for a fuel code. Thanks

I ducking hate GM.... I'm sticking to Toyotas from now on. 🤬

Carbon buildup on the valves? Top end cleaning? On a gdi engine? I think somebody may have read the signs wrong here. Gdi engines ONLY flow air across the intake valves. So no carbon buildup should be present there. Gdi engines also burn more efficiently so less or no carbon deposits should be present on the exhaust side though. COLD start rough idle is usually caused by shrunken intake manifold seals. Since they don't have gaskets anymore, the rubber seals tend to shrink over time and will leak air until they heat up and expand enough to seal. I usually like the videos produced by this channel. But I'm fairly certain they missed the bus on this one.
