Come along with Eric O. at the SMA shop as he looks into this "low power" complaint on this Nissan Frontier Pickup. We also get to bust out the Pico Scope to aid us in our diagnostic and learn how it can tell if the exhaust is plugged.

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!!!!

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 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

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!

My first test on a car with this similar issue is is take it down the road. Give it gas tell it starts choking out and pop in in neutral will my foot still on the gas. If the rpms go up it’s most likely a fuel delivery issue. If not looking more like catalytic converter. Great work! Love the videos

@mrmatt7210
@mrmatt7210 5 лет назад
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.

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.

It was even audible after you shut the engine off, the hiss of the pressure escaping. (obviously could also have been AC low on gas/evap purging or similar so wise to diagnose with the scope and pyro too). First time I've heard of it occurring suddenly though like you say, normally takes a while and in my experience usually plugs up the back box. Wonder what state the 2nd cat was in, too, having been bombarded with chunks of porcelain?

@thomascoolidge2161
@thomascoolidge2161 5 лет назад
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.

starving for fuel, pump not delivering or (suddenly?!!) clogged filter was my guess ... no, he looks at gasses... pressures... Thank you for the lesson!

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

you could have done a running vacuum test too. when you rev it up if the vacuum doesnt drop hard, your exhaust is plugged up. ols skool test that still works on any engine.

I'm impressed by your tech and mechanical knowledge. Hope you're starting to recycle in electric cars cause that's coming soon and all those technical tools you're using right now will be obsolete. But I see a future when old school mechanics will be rare to find and command high premium fees to maintain private car collections from rich dude or nostalgic track racing enthusiastic. Having knowledge in both old and new technology is good for your business, STAY AHEAD, it will make you invaluable and one step ahead of others. THIS IS A MESSAGE FROM OUR FUTURE.

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.
