#4 of 73 Re: 03 tundra oxygen sensors [woodgreenfarms] by ppisano Jun 15, 2006 (6:07 am)
Replying to: woodgreenfarms (Jun 07, 2006 11:32 am) ok, the update. I replaced the spark plugs, I cleaned the KN mass air flow sensor. 300miles later I got the po161 code again. I'm really perplexed right now, I just may replace the cat system as thats all that left for thet system (i think), remember I already replced the 02 sensor and the code came back. I'm assuming it's noty the new sensor. Maybe replace the cat system. Any ideas left??

I am wondering will things function without these o2 sensors. Is there a way around it somehow?

I was told that on some Toyota vehicles that you have to replace the mass air flow sensor to realize the full benefit of a cold air intake system. Is this true? I am also curious as to the noise level of the Borla cat back system. I have decided to spend some money on my current Tundra to prevent the purchase of a new one. Thanks.

I have a 2004 toyota tundra I just bought and notice that when I start it up when cold I get a lot of blue smoke for a few minutes than goes away I had it check out at the dealer and they said everything was fine, I really don't like it, I did not notice this when I bought it two months ago, could it be the oil? its running standard 5-30 oil,they say no, some say use synthetic oil does this help? I only have 36000 miles on it, it does have a superchager and headers with daul exhaust from the factory. any info would help. Replies to this message: alps (May 21, 2007 8:40 pm)

it sounds like worn rings or valvue guides.have a compression test run to see if all the cyl. are equal & up to factory spec.

Replying to: gts4 (Apr 08, 2007 8:06 am) I was a diesel engine mechanic in the navy a long time ago, the other party that replied to you, is probably correct. I would probably suspect the valve seals and or the rings as the rulpret. And I want to ask, a supercharger or a turbo- charger. There is a distinct difference. Is it belt driven, or powered off of the exhaust. If this is the case, either way you are probably running to much boost; which would cause the seals on the valve or too much boost would be putting too much pressure to the indiviual block bores. That maybe why you are experiencing the deadly blue smoke. Be concerned!

Did anyone ever post a link to a PDF on changing the oil filter? What a hassle. Other than this, I love my truck! Replies to this message: exf150owner (Jul 19, 2007 3:33 pm)
