I said(out loud) to my phone "Plugged cat" at 0:38 of the video. I'm not a mechanic,per se,but had plenty of experience with plugged cats. Bought my first brand new vehicle in 1998,a 3.9L Dakota sport pick-up. It had a total of 83,000 miles when I traded it in and had been thru 5 CATALYTIC CONVERTERS. Exact same symptoms as this truck but with enhanced rattle. Went out every 15,000 almost to the mile! Didnt find out why,didnt really care. Got rid of that POS and never looked back! Enjoy your videos!

I just wanted to say thanks, I watch your channel quite often. I recently acquired a $550 "towyard-special" 2001 Xterra with a KA24DE. It was running terribly and I was able to identify a blocked upstream catalytic converter with the aid of this video. $95 for an eBay cat and no more CEL. Keep up the excellent work bud.

I just starte4d watchina g your videos recently. I am 75 years old and my very first car was a 1955 Chevy with a 265 V8 which burned oil so In decided to tear the engine apart and relace the rings. I got most of my tools from Sears and parts by mail from J C Whitney catalogs. In 1963 that was the equal to Amazon today for cars and truck parts. I got it done and all reaasmbled but Im ended up with 2 bolts left over. Not a clue where from. The car ran well for a while but then started to burn oil again. So I took everything apart again and found out that I left the 2 bolts off the main bearing cap on the crankahaft. Solved the mystery of the 2 extra bolts. I enjoy watching auto repair videos but the electronics lose me. Keep up the good videos Pete

Hey! About 4 years ago here in Armstrong County PA I used a similar cleaner to what you guys used on my old 2004 silverado pickup. I believe it was called "sawzall, exhaust tube bender, and straight pipe". Kind of a weird name for a cleaner but it worked better than ever and sure cleaned her out. Only one cat was plugged (there is one on each bank of the 6.0 v8) so the truck was running really really weird. Also I was able to use the "hp tuners" "tune up" software to take care of my new false check engine light that came on because I used this cleaner. Took care of that and actually plugged the truck into my friends emission machine and it passed! Yes is passed after that!! That tune up software really works!!!!

Eric was excellent in diagnosing a bad catalytic converter. With this in mind, there are two points which may be of assistance to viewers of this video which are having a similar problem. First, the rattle noise heard coming from the exhaust is most likely the heat shield on the front catalytic converter. Over time, the heat shield will become loose and deliver the "Nissan Rattle". In such a case, a stainless hose clamp placed at the appropriate spot will remove this noise. Secondly, you may have a vehicle which still has a warranty in place. Though your vehicle is outside of the standard 5yr/60,000 mile factory warranty, converters are covered by an emission control warranty for 8 years or 80,000 miles. Dont spend a fortune on a repair if you dont have to.

In the old days, we diagnosed a restricted exhaust with a simple vacuum gauge. Start at idle and slowly bring the throttle up. The vacuum should go up as engine rpm increases. If it goes down, the exhaust is restricted.

I had a similar issue with my 2012 Nissan Frontier with the 4.0 liter engine. They replaced many parts at the used auto service department and still couldn't fix the issue. Issue: loss of power out of the blue and when engine would warm up. No engine check light. Engine thermostat was reading high but not in the red. To make a long story short, the Nissan garage had it for about 15 minutes and found it was a bad thermostat. Because it was overheating, but not in the red (danger zone) the system would cut power to the engine so it wouldn't destroy itself. Great video. I would just tell people to make sure and take your vehicles to a reputable mechanic. I was without my almost new truck for about a month and a half because the service department at the dealership couldn't diagnose a simple problem.

Definitely worth taking a little bit of time to get a feel for the metric system. The best way is to give up on trying to convert to imperial, and just go for thinking in metric. 1 metre = large 1 step, 1 centimetre = the width of your little finger, 25 degrees celcius (or centigrade for USA folks) = a beautiful sunny day. Metric is excellent when you want to convert weight to volume, because 1000 litres of water = one metric tonne.

Wonder if the misfires took the cat out or if the misfires are associated with the failed cat. Curious if you still had the misfires after you changed the cat if your got the job...unless of course you video'd it and then I guess I'm just going to have to wait. This is where diagnosing with a lab scope helps pay for itself & saves you so much time. You didn't turn a wrench or get your hands dirty other than removing the sparkplug but definitely better than stripping out an AFR sensor to check back pressure! I love my Pico & thanks again. Great diagnosis as usual & hope you got the job.

The ceramic inside a catalytic converter is made from fragile material. It is typically protected by an insulating mat. This mat holds the catalyst in place and provides moderate protection against damage. However when anything strikes the converter or a broken exhaust system support can cause this catalytic material to fracture. Once the ceramic catalyst is fractured, the broken pieces become loose and rattle around and break up into smaller pieces. Flow is interrupted and backpressure in the exhaust system increases. This leads to heat build up and loss of power.

Have a 2002 Malibu that did this too. Brother was driving it down the freeway and it just lost power. Limped it home, started diagnosing a fuel related misfire, discovered it was a badly plugged converter. Took the EGR tube off running from the exhaust manifold so it could quit choking on its own exhaust long enough to get it to a shop for replacement. It's happy now, I guess after so many miles they just call it quits.

I wonder when he had oil in the plug wells if he drove it long enough with it misfiring to load the cat with gas? Too bad he is past emissions warranty as well. That part is going to be expensive. So the cat and manifold are all one piece on that? Wow, that's crazy. Cool checking for the exhaust restriction with the scope, great video.

Yep they are all one piece but it wasn't to bad, about $500 for the factory one

Every 10C = 18F. Add 32 at the end and there you go. For kms, multiply by 6 and then divide by 10. You'll be off somewhat on large conversions but it'll get you in the ballpark.

Over this side of the world we take f- reading, -32, divide remainder by 2, = C.

if you want do the exact conversion, the easiest way in your head is double the temp in C, take away 10%, add 32.

Nice discussion at the end. Sometimes due to the rules we have to swat flies with a sledge hammer. I intend to mow the yard today and my old mower is going to pollute more, a whole lot more, than the cars driving past as I mow.

I had one but the 4.0, hated that "truck". Twice it had no power, once converters clogged, 2nd throttle control wire broke. Had multiple issues with it. I gutted the converters, got the best milage it ever got, had more power than it ever had

Nice video Eric. Using the pressure transducer to diagnose the high back pressure in a cylinder was pretty interesting. I'm not sure if i would have thought of that. I'm surprised it didn't throw a P0420. If it was me I'd cut open the manifold pipe, remove the catalyst to make it drivable and then sneak across the border and get a cheap one put in. It isn't worth putting an OEM cat on a Nissan of that vintage.

The DIY cowboys definitely have an advantage over you in this department. Must be good business for the shops just over the border in PA in converter replacements.

The cat plugged up on a Chevy S-10 suddenly and it wouldn't Rev beyond 2k, I unbolted the exhaust on the side of the road and drove it home dragster style, then bought another replacement cat and welded it in. They can plug up suddenly.

I had a 98 dakota do this. Except it would run ok, low power but it would accelerate. Then as you drove it it the temp would climb then it would start overheating. Cat was plugged. Thought it was fuel related issue as well. The temp rise was a good indicator.

In my career Nissan's are notorious to plug up cats and even the ultima's the cat material would go back into the motor and wear out the cylinders and rings and you are right that AFR is a bit pricey.
