Very interesting! I was always under the impression that when the MASS sensor was bad, the fuel trims would get worse at higher RPMs. This proves just the opposite in this case. Maybe the other scenario is when you have a dirty MASS. Thanks for posting this one, it was very informative!
Frustrating. False economy to cheap out. Don’t know how many times I have seen this movie and still not learned the lesson. Being a cheap bastard is expensive at times 🤣 Thx for watching Brian 🍻
The government expects ordinary people to comply with their emissions regulations, but they'll allow parts to be sold that are out of tolerance by 20%. Its time to start punishing the sellers of garbage. This could have cost some single mother thousands in parts cannon misfires, just trying to pass a atate inspection. At 20-25% of fuel trim, many cars will atart throwing check engine codes. Tenacity is a good word for OCD behavior that leads to success, eventually.
Good question 🤔 I had my suspicions about the MAF idle value. Likely injector balance test and then endoscope the intake manifold for restriction (carbon buildup). Thx again for watching and your comments 🍻
I saw a similar aftermarket MAF sensor case study, 99 Subaru Imprreza, a Subaru Top tech chased his tail, had break-out leads installed, scoping, measuring, gathering data, forget the rest, but he eventually installed an OEM MAF, all fixed.
Both of these cars have the two liter right? I've heard the rule of thumb that the grams per second at warm idle should be just slightly above the displacement in litres. In case you don't have a known good part... or car for comparison! Looks like a Bendin reference 😁
How long ago did you install the Delphi MAF? From my experience, aftermarket MAFs are a waste of time, if they work at all out of the box or last any reasonable time, they're a waste of money. I quit using aftermarket sensors years ago. Genuine Bosch, Denso, or Hitachi is the way to go. And I'd avoid purchasing from Amazon or eBay, lots of counterfeit stuff floating around these days.
@@TheGibby3340 A couple of years, not bad, you got your monies worth. 🤪 Your son probably delayed reporting the symptoms for fear of not having his car due to its YT production value 🤪

Thx Bob. Yeah I learned a little on this one. Thx for watching 🍻
huge luxury having a spare car for parts swapping
I like the mechanical hand👍
Certainly is. You were one of the few who called it Denis. Thx for your suggestions and watching 🍻
Its like watching a main dealer at work 👍😁.
🤣 Start swapping bits. You’ll eventually fix it 🤣 Cheers Iain
Nice find…I’ve had more and more issues with “quality” name brand aftermarket parts, especially sensors.

I’m not sure if your final sentence is a complement or an insult 🤣🤣🤣
Heres a question; how would you have proceeded if you did not have an identical vehicle available?😉😉

@hnd2893 Not the first or the last. 🍻

Yeah both are 2.0L gasoline. The only engine option in Canada are far as I know. That rule of thumb sounds about right. Thx for watching 🍻

Couple of years back. Only recently did my Son report the stumbling. As usual… false economy to cheap out. Thx for watching and your comments 🍻
