Oopps! I almost forgot! Do Not over-OIL your air filter as this will release some of the oil and contaminate the MAF meter (hotwire). some dust may bypass the filter and stick to the hot wire, eventually will set a lean code PO171, system lean and make you FJ run like cr_p! Easy to Fix! LOOK at the MAF hotwires, if it is dirty,clean with contact cleaner and let air dry!  |
I missed this post somehow? What is the filter behind the filter? How does oil get to the MAF sensor with this in place? How do I find the MAF "hotwire" I think that dust has made it past my second filter. I think that I need to clean this out. Thanks for any an all help.

I just had mine reset yesterday. The chief mechanic at Toyota said that it will relearn in time on it's own, just not as fast as it would if you have the learned values reset (relearn ECM). After it is reset, they recommend that you drive around a while, varying speeds as you go, so it will start to relearn your gearing. That is why I believe this to be important especially when larger tires are put on.
Your performance and gas mileage are going to be better if you start from a clean slate in the computer memory.

What did the dealer charge for this? Mine sucks and I am sure that they are going to ask me what this is when I as for it? I had to explain what A-Trac was to there master tech yes A-Trac he said they have many systems on there cars and he can not know them all.
Thanks you all for any help.
