Hi, recently my check engine light has come on with codes p2099, p2097, and p0430. The catalytic converters had been replaced recently but now the p0430 is back. Took it to the shop and once they got it on the lift they brought me out and showed me that the previous owner of my truck installed their own "drone pipes", and the techs claim that is what caused my relatively new cats to go bad. My question is will replacing the exhaust system in full be the correct fix, of may there still be something going on the harm the cats? Thanks

Ah yep just what I thought.

 

Do you have Flowmasters?

 

Those pipes help cancel 2k up drone, by way of sound deadening those frequencies. Old trick. Likely not the cause of your issue.

 

Do you have headers?

No aftermarket headers, in November I had a Jasper reman. engine put in, it's a afm delete model, meaning it's just a simple pushrod gen 5 Lt 5.3 with absolutely no afm bullshit. Factory headers, muffler is a magnaflow magnapack.

Did they use the correct OE converter y pipe assembly?  Did they install new OE oxygen sensors?

It looks like they used magnaflows 50 state compliant system. When the light first came on for me I replaced all o2 sensors with acdelco's

After market cats usually always set the check engine light sooner or later. That doesn't mean they are bad, it's just that they are not as good as the OEM.

 

You can try spacing the rear o2 sensor out of the exhaust stream to try and stop the code from coming back, it's a popular trick to do.

 

Past that you could get someone to tune it and turn off all of that garbage. If you lived close to me I'd only charge the cost of the vehicle license for such a simple thing.

Cam is spot on. 

 

Side note once you get your o2 sensor issue squared away try a different exhaust setup and scrap the drone pipe. It is in the wrong place anyhow. It is supposed to be more over the axle.

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
