    I just replace the Air filter even though it was clean. I will clean the AF sensor tomorrow. I will also get the coolant temperature when it's below freezing. What temp should it be?

    Thanks!

    It should read close to ambient temp if you dont start it.

    Thank you Dave!!
    I cleaned the MAF sensor and so far no p0308. I'll wait till spring or summer to replace the O2 sensor since I already made the purchase.

    Nice, glad it worked out for you. Could you return the O2 sensor? Who is the manufacturer? Some of the aftermarket sensor are not reliable (Bosch).

    I got it from Amazon, Denso brand.

    I suffering with poor gas mileage. 10-11 mpg in city. I was able to do 12 -13. My 2016 and 2020 Tundra was never this bad. I am thinking there's an underlying issues that the ecm try to compensate but not severe enough to trigger a CEL.

    Any suggestions where to start and parameters to read? I do not have techstream, but my Launch reader can read almost everything.

    TIA

    You mpg should go up now that you don't have the P0308. If your running 33s LT tires has mileage will suffer. Are you running a lift?

    Denso makes a good sensor. Which sensors did you buy? Pre cat or after cat? How many did you buy?

    I bought both last left and right. Post cat i belive. Pre cat was called air fuel sensor.

    I do have a lift, 2.5, but I was having better mpg before the move to Canada on 295.70.18. Mpg pulling the trailer from Florida to PEI was 10-12.

    Welcome to Canada, cold weather kills mpg. Around town, cold weather, lifted and bigger tires all hurt mpg. Remember your computer won't report the correct mpg because of the bigger tires. You have to hand calculate.
    You could try the air/fuel ratio sensors but I suspect you won't see any major mpg change. If you don't mind me asking what did the sensors cost?

    61.13 and 66.32 coming from the US shipped to Canada 146.45 USD The AFR sensor is more expensive than the O2.

    Go to know about the colt temps and mileage. I had no clue about about that. I know being lifted and larger diameter tires impacted my mileage, but did not know about cold weather condition affect it too. I know I waste a lot of gas with the remote start 2 to 3 times if the truck sat overnight and temp drops below 0.

    Thanks wo the warm/cold Canadian Welcome! Most people move to the warmth when they get old, I moved to the cold. LOL!

    This is how I got the package from Amazon. I'm not sure if the gap got compromised. Can you re-gap iridium spark plugs without damaging the tip?

    I have plenty of experience with re-gaping and even sanding conventional spark plugs, but with the iridium, I just install it as is.

    TIA

    Measure and check. The gap is probably OK but I would definitely be in touch with the seller. If you do find th gap out a touch you can adjust but my concern is that if it took that kind of a hit the porcelain may be cracked.

    I did not even think about the porcelain. And it's going to be hard to tell if it had a hairline fracture until it fail. Thanks!

    You could end up putting them in and have a misfire. If the gaps are ok and the package was padded well they would probably be ok. If you find some gaps out of spec or different from the others I would send them back.

    Just out of curiosity, what's a swing arm type or plate type lift? This apparently came out of the service manual and was posted on tundrasolutions.com. Wasn't sure if that included my standard floor jack I've used for other cars.
