New truck shopping

Thanks!
Yeah I was thinking Bosch was probably the way to go...those come with anti seize on them already though, no?
I don't recall now which one is throwing the code...but I've reset it a couple times now and it takes a while, but eventually the light comes back on and its the same sensor...must be getting lazy...debating if I should just do the one or bite the bullet and do them all...I know you'd likely want to do them all on a 2003 with 170k miles (probably not the original sensors though) in a repair shop environment, but for me just DIY...and don't put that many miles on...I'm leaning toward 1 at a time...
EDIT: Ooooo...just seen AutoZone has price cut and $20 each rebate on 'em

 

Is the code o2 heater circuit or sensor performance? Heater code is not so critical, performance affects fuel mixture/mileage. I would do both the upstream sensors as a pair. Kinda like putting in all the spark plugs. Your mileage & drive ability will improve.

 

So upstream/downstream as a minimum is more important than doing all 4?​

99% sure it was performance...I don't recall the code # now...the light is on now again, I'll check it and PM it to ya so I don't continue derailing Horkn's thread with my "not new truck shopping"

 

Just curious if General Motors announcement to close 5 plants in North America factors into anyone's new truck buying decision?

 

Nope, my "newest" truck is a 1999 K2500 Suburban that I'll keep for a while yet, just can't make myself spend the $$$$$$ for the truck I'd want.

 

If there lazy 4 is best. But do the upstream ones as a pair. They control the air fuel ratio. Lazy is not good. The down stream ones control it but to a lesser degree. There basically there to watch the Cats to give the ECM feedback on whether there working or not. If the two feedback waves are close or it keeps switching lean to rich once hot it triggers the codes for the bad or low function catalyst. So a bad downstream one will not hurt mileage as much. It will put your CEL on though.

And yes if it's a heater circuit code it still functions fine once it warms up after several minutes. The heater just Pre heats it so that it can function sooner to get you into closed loop sooner. I rode around for yard with a CEL on cause of a bad heater code. It was about impossible to get that one out on the Highlander. When I did the plugs and pulled the intake plenum off I did it then cause I was just able to reach right down to it from the top, in a way I would of NEver been able too before.

 

I like older stuff. And I would like a newer truck too don't think I wouldn't, I just can't bring myself to make that big of a payment t every month for like 7 years. I just don't like riding around in one that much!!!. Our newest ride is the wife's 04 Sequoia. We love that vehicle! It's like a tank. Not as big as the newest model but I like the simplicity , relitive, of the first gens.

 

That truck only has two 02 sensors.

 

I've never been a fan of GM. I just add this to the list of really bad things they've done over the decades.

 

Hmm...now your gonna make me go out in the cold to crawl under this thing and look...
I was almost sure there's more than 2...but, I haven't spent much time under this truck either...such is the life of a Ford owner

 

He is a mechanic, I would probably believe what he says......BUT having fords I know they did some weird stuff, like your 95 having over the left over alternator from the previous decade or your brakes not mathing what the other 11 months of production were.

 

That isn't just Ford, they all do it...ever work on an older Jeep? What mutts those were!

 

Yea ford stuck out to me as the worst, also Chrysler Corp I remember. I worked at a parts store for a year or so and Ford seemed the most common to me...at least. But I am nor was an expert.

 

yep new production model first couple months will have what ever is left over from previous run if it will work. Then there are the various vendor changes during production / parts upgrade/ substitution which complicate things even more. Best to have your vin number with you at all times when buying parts. I needed to replace an axel seal a couple years back had the old one with me nothing at any shop was even close- even the stealer ship part was a no match. Ended up just reusing orginal and a lot of RTV. Another little ditty is weather or not it it may have been produced for commercial vs public ( police , fire ect)

 

Ahh, yes, the police alternators, upgraded brakes, different heads, suspension, etc. I hated old police cars. You never knew what was on it, what had been hacked and converted back at what point etc.

 

Found some completely back to stock,some looks like take the decals off,light bars and off to the auction

 

XXL I can't blame them for shutting down plants for vehicles that are not selling. They're shutting down the plants that are design for the small cars. That nobody's buying.

 

The plant here in Oshawa Ontario that is scheduled to close next December is currently making the current pickups and Impalas. The truck plant has been working 6 days/week for the past 7+ months to try to keep up to demand.

 

XXL apparently American News only tells the American side of the story. It makes no sense themshutting down a truck plant! As they can't keep up with demand. Ford's doing same, only car they will be producing in the future is the Mustang.

 

I am sure there might still be a car for fleet? But not sure? They will make the escort crossover or something. But that's a crossover so kind of an SUV
