In this video we have a look at a 2002 Chevy G3500 Express Van with the 5.7 liter that has a customer complaint of “bogging, lack of power after a hot soak.” This is a fairly common complaint and symptom. It can be caused by many things such as a plugged catalytic converter, a failing fuel pump, or as we see in out case an oxygen sensor that is on the fritz! -Enjoy!

If the engine is still cold doesn't it make sense for it to be still running open loop? I thought the closed loop temp on those was 180f or so.

love the snow removal teckique go fast wish for summer

XYourexMyxSaviorX says:

To add a small bit of info Eric O. GM vehicles will not enter closed loop unless all the o2 sensors have fully come online and are producing voltage

I had a 2009 Chrysler 300 6 cyl 4 wheel drive.
I could defeat the computer on take off by fluttering the gas pedal.
engine would die for about 2 long seconds.
sometimes in stop and go traffic it would die out for about 2 seconds also if you were heavy on the throttle.
no it wasnt ABS
watch your rail road crossings

Tom Gill Chevrolet says:

Nice work man. Great video – thanks for sharing

codybroken says:

Half what you say goes right over my head, but it's always fascinating. If there was an automatic thumbs up feature for YouTube I'd set it for your channel.

Bill Neu says:

Hi Eric, you are a true American and a skilled technician. You are an Educator, thanks for the scan tool lesson. If I can do it you can do it. I believed in that thinking my whole life. Bill N

Get one of those holders, attach it to a tripod. DIY "Universal shimmy scan tool holder". Something like this, or BYOB https://www.amazon.com/Products-Vehicle-Laptop-Notebook-Holder/dp/B003XNOJEO/ref=sr_1_6?ie=UTF8&qid=1518026230&sr=8-6&keywords=automotive+laptop+stand

HUBBABUBBA DOOPYDOOP says:

Quick & dirty is to snip & solder in a "universal" part- I know it takes time, but don't you have a re pin kit? It would've been just as easy, and a dab of silicone paste on the gasket & wires. https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=auto+wiring+connector+pin+kit&rh=i%3Aaps%2Ck%3Aauto+wiring+connector+pin+kit

JOGO says:

Well done sir , thanks

Gordon Freeman says:

Just like a good guitarist having many guitars, eric needs his various scan tools.

Mike Holt says:

I know when I get a bunch of junk in my truck bed I leave the tailgate down and get on the highway.i call it a self cleaning bed.

David Woodbury says:

Thank you have a good day your videos are great have a good week

David Woodbury says:

I'm not sure if this means anything but I was looking at all data a long time ago and they said to do something with fuel injections and it said for something like symptoms like that but it doesn't matter anymore I don't have the vehicle anymore

David Woodbury says:

You were talking about Chrysler vehicles having that same exact problem my Jeep Cherokee with the 6 cylinder 4.0 head the same exact problem. No longer have the vehicle if this makes any difference is a 2001 thank you and have a good day

Bryan Tasler says:

Don't. Use. Solder.

William Fowler says:

The old banana in your tail pipe symptom. Nice ride. I like something I can get out of.

Adam Trombino says:

A lot of those GM 3/4 and 1 ton vans and trucks nearly automatically pass a cat drive cycle despite what real time o2 data says. It a programing deal. In your case, it was old enough to say not supported, but I've seen several 05-09 say 'pass' when indeed they are not even looking at cat pass/fail data, not running the cat test, and the cats clearly weren't working. So long as the continuous and o2 monitors pass, these are the easiest to sneak through emission tests for failed evap problems. So much for the polar bears!

Vivian Stimpson says:

Have you noticed, with Vise-Grips and WD-40 you can fix just about anything ?
Love GM vans, glad it wasn't a nightmare to fix. Thanks for sharing. Spring's coming…

inverlass says:

Tool poor… I Need better tools. I have, laptop based tools, but it's a clunky to set up and time expensive. [Renault Clip, Ford IDS5, Mercedes Star Diagnostics]
Choice is buy a good secondhand car or buy a Autel Maxisys Elite.

dave C says:

Love your videos, just upped my patreon pledge, you do such a damn good job of explaining the what’s and how’s of your repairs…. again thank you. Dave.

TheRationalAnarchist says:

I haven't watched the whole video yet but I had a very similar problem and it turned out to be a bad cat.

Jamie Dodd says:

You mentioned that you used Bosch brand O2 sensors. I heard that that brand doesn't always work properly on GM vehicles. Denso is the OE supplier for GM, Denso O2 sensors might have been a better choice for that vehicle.
