In this video I bring you along as I have a look at a customer's 2013 Chevy Silverado with the big 5.3 that has codes P219B and P219A. These are fuel trim imbalance codes (cylinder to cylinder fuel imbalance.) These codes can be really tricky to point at something tangible and make a call on a faulty part. In this video I discuss some of things I look for on these vehicles when faced with these codes.
-Enjoy!

It has been about a month and a half since I fixed this vehicle, and the guy is happy as a clam. No engine light, drive cycle complete, passed emissions inspection and fuel mileage back to what it should be. Hope there was some useful tidbits in this video to help you on your diagnostic path. -Eric O.

As a South African I am pleasantly surprised by learning that the USA is one of 15 countries worldwide that the Bearing Man Group is doing business in!! This group was started in 1974 as a single person business in a garage in Durban, South Africa! A great success story and Proudly South African! Thanks Eric, I enjoy all you very informative content, especially the way you presented it. Keep it up. Jan Cilliers, Clanwilliam, Western Cape.

It's nice to see occasional videos like this that efficiently deal with a problem that can be difficult to pin down. Having an algorithm or checklist prevents the dreaded callback that ends up throwing mud at bystanders. Even in the DIY setting sometimes you want to just fix it and move on with the day. As you say, these kind of videos are underrepresented because everybody wants to focus on exact diagnosis.

Learning how to diagnose fuel trim codes is critical to any diagnostic routine involving them, especially when they go lean. Thank you SMA.

It's not just the knowledge that makes this shop great, it's the honesty. Having said that, it really does start with the knowledge and that's what I love about SMA!

I have found Rock Auto to be straight as to the brands they sell and selling genuine parts. They sell a range of parts from different companies so you can choose your price point. The GM brand parts are still less than at a dealer, but not the lowball prices on Amazon or eBay.

Good job Eric , a big take away for me from this video is to not over look the simple basics! For a lot of people they would not know that the broken air box lid can be a contributing problem!

These types of videos are actually very relevant to all types of car models. You covered a lot of possible causes & solutions in almost 19 minutes.

Last year my stepdaughter purchased a very nice car for her daughter, with a dirty MAF, exhaust leaks aftermarket exhaust parts, and 8 hard codes(to make it short).I replaced exhaust parts , cat back, ABS wheel sensor with a broken wire and cleaned it up for NYS inspection. Thanks to the walk thru on your diagnosis I was confident with my thought process and found aftermarket parts “Dor” were most of my issues! Keep up the good ,ride along videos, they inspire us all! FYI she is 17 with 2 small dents added to the patina, fence post and a garbage can.

Eric has become a wise old man. His voice is an octave deeper, his beard is the colour of experience, and he's about a foot taller compared to when he first started the channel.

As a random YT jabroni, I enjoy watching you go through your troubleshooting method. Your no-nonsense description of the problem and the fix is easy to follow and your sense of humor easily make you one of the best channels on this platform. Having said that, if you goto Wilburts again without us or forget to put in the sound affects when you grab the fluid film or break clean, I'm gonna riot! 😁 Have a great day Mr. O

I got O2 sensors online ONCE, they were so different I didn't even attempt to install them. The originals had different wiring and clip, I ordered GM OEM and the box said GM so I contacted the "well known" company about my problem and they tried to tell me those were "original OEM" when I pushed back and said I have pics of both they refunded the $ and told me to keep the ones they sent me. Like I said, this was a well known online parts company, I gave them the worst review I could without the salty language. I got the replacement OEM sensors at Advanced at a comparable price so "brick and mortar store everytime!!! Thanks for your insight, I love your show. Lifelong wrench turner ✌️😎 PS. I also ordered a trans line OEM GM and got a Dorman that kept leaking at the trans side, same results. Needless to say they don't get my business. 😎

Really great information on those codes. I’ll never buy another GM product after watching years of SMA.

The 2013/14 Tahoes I have had over the years have been plagued by those codes. I chased them for a year on one, used NTK/Denso forward 02 sensors and they kept coming back. OEM sensors fixed it.

Educating the consumers seems to be a big part of who you are. Thanks for the info....... price isn't always the best answer!

Funny bit of info...my wife works for the post office which happens to be very close to a GM dealer. They recently started ordering A LOT of their parts through Amazon. They said they're cheaper than what THEY can buy them for through GM. That alone screams counterfeit if you ask me!
