3.4L supercharger

That's a good point. Same here. I live at 1800 feet but I work at -16 feet.
My truck isn't my daily driver at least. I have a car and motorcycle for that stuff.

 

I’m feeling it now. They disconnected the battery to put it that hose.

 

yeah. I was reading up on that. Passenger planes have superchargers to make up for the lack of 02 as you go up in altitude. So the supercharger would force more air to get the plane to keep going. The guys that live in Colorado need superchargers. It’s a must LOL.

 

thata what I’m trying to get used to. Staying out of low RPMs. I liked to chill in 4th gear. Now I chill in 3rd. I chill with 4th gear on the freeway up to 70 mph. My gas mileage is “fill up everyday”. The ECU is adjusting. But I am driving a lot. And carrying a bunch of stuff. My LX 350 wheels are 3 pounds lighter though.

 

Well I think there is a problem with these sensors not being OEM.

I bought one from this seller two years ago and had no problem and it was 45.00 or so.

I bought two last week at 16.00 each and put one in yesterday and the truck was running great.

Today I can’t go over 4000 rpms without the engine boggling down and my AFR is at 9.5,
Screaming rich.

I put back the old MAF sensor and the truck is running excellent except the trims are high.

I open up the 2nd MAF sensor that was going to be a spare and it had a sticker that said MADE IN CHINA.

I’m thinking he’s selling fake one now, not OEM DENSO that he had before now and the stamping is different from the original DENSO I got before.

Maybe one is defective but I’m returning them both.

I not sure DENSO made these in China tho?

Guess I might bit the bullet and go get one from the local dealer.

 

The fake DENSO electronics usually don't have a date/serial code stamped into them.

 

This is the one that I got, says made in CHINA on the bag.

Truck will not run over 4000k with this sensor without bogging and stumbling

 

Man these fakes are getting good. That big C on the one you got that is problematic seems a thinner font than the "authentic" one I posted. Pretty much a shit show out there to find reliable good DENSO parts these days

 

Interesting, yup the “C” is smaller on mine assuming the photo you posted is an ORIGINAL is thicker.
Didn’t notice this till now,

Oh well off to the dealership

 

$220 At Stevinson Toyota East

 

Ouch

 

I know. I was going to pull the trigger on that. But I’m just going to put back my original sensor after I clean up.

 

Camel back has them for 138.00.
If there’s one thing I know it’s best to have OEM sensors for these trucks

 

That’s a better price than $220.

 

Yeah it really is a gamble buying sensors online anywhere but a dealership.

I've had good luck buying Denso sensors in person at places like AutoZone too, not always cheap but I have rewards points with them sometimes that makes them cheaper

 

Just smoked and infinity two door double exhaust car pretty damn bad. LOL It was going uphill and the ECU is still meranading.

 

Don’t try it on an Audi turbo tho, hehe

 

It’s to important of a part, just going to get one from the dealer

 

It’s the same with me. I can be at light throttle and take the RPMs nice and slow from say 2000-2500 and at 2500 I stomp it or chill depending on what I’m doing. But I can drove normal at any RPM with light throttle.

 

It definitely would suck to have to deal with pinging all the time after installation the 7th injection.
Does not make sense you have a ping issue with the 7th injection is what I’m thinking.

Are you running a stock pulley?
What boost are you pushing?

Have you done a checked list of items for the pinging?

Carbon build up in the intake or pistons?
Fuel pressure line test by the drives fender hose?
Replaced the fuel filter under the cab?
Fuel regulator is working correctly on the back of the rail, vacuum,?
Your long fuel trims? Running high?
Possibly dirty fuel injectors ?
MAF not working correctly ?
