Grr Check Engine Light @ 87550 Miles. 90k Service?

[el_madmaster]

Hm got a check engine light at 87550 miles. A bit irritating after recently dealing with an ABS light, a VSC light, and Airbag light that cost me a pretty penny for those and the damn ECU thing frequently mentioned on this forum.

This is probably way too optimistic, but is it possible that this is related to the 90k mile service? The car still runs absolutely fine. I am going to go in to see what's up soon. Any ideas what it might be around 90k miles?

Many reasons - see attached

Damn turned out to be the Bank 2, #1 O2 sensor, which explains the check engine light. I also have leaking manifolds. Explains my drop in mpg I guess.

So now my Sequoia has had just about every common problem on this forum. Blah.

They quoted me 1700 for the O2 sensor and manifolds. Does this sound reasonable? I've been checking around the forum. Can that O2 sensor be done yourself easily? If so, how?

And JBA or Gibson headers sound like a good solution for the manifold. Also read that it wasn't for the faint of heart. Is there a list somewhere of all the tools you need, and directions to install it? If you're not terribly experienced, would it just be better to have a mechanic do it? Otherwise, how much would you guys say it costs to install?

I would OPT for the JBA headers. They are the EASIEST to install and my opinion the best all around header. (There are many opinion of which header is best, this is just my opinion, not trying to start a debate)
I would not pay more that $300-400 for the install.
Here is a place that has the JBA's on sale for a good price.
JBA
Another TS member just bought them and is having me install them next month. You can change the 02 at that time and shouldn't cost any more, they have to be removed to change over to headers anyways. Make sure they spray WD40 or equivalent and let them soak for 30minutes so they can be removed easily.

those o2 sensors should be covered by an extended warranty, I would Raise F-ing hell, with so many problems in regard to cracked manifolds and bum o2 sensors. look at what a good toyota man you are, a tundra and a sequoia, I would call Toyota customer service too

[el_madmaster]

I take it you have installed them before yourself then. I've heard varying amounts of time it takes to install them. How much would you say it would take? Since JBA is just a bolt on, though apparently some contortions are required, could a novice with the right directions, the right tools, and enough time install them decently?

I'm away from home and won't have the means or time to do anything for a couple weeks. I spoke to an exhaust shop back home and they said they'd like to take a look at the manifold first to see if they could just weld it, and it was also possible that the leak was tripping the O2 sensor to believe the fuel was too lean. Or some similar explanation.

O2 sensors are definitely a DIY job. You only need a special socket to tighten down the new sensors, and it can be borrowed at Autozone for free. I bought the universal versions, so I had to graft the old plug onto the new sensor. Total time was about 45min, including the frankensteining of the plugs, not difficult at all, and it contributed to restoring my gas mileage to like-new levels. It didn't require much flexibility on my part, and the sensors come with detailed wiring instructions to connect if you buy the universal versions. If you buy the application specific ones it's even easier but they are much more expensive.

Mustang - any need to pay for the upgrade to the ceramic coated JBA's over the standard stainless steel headers other than just for appearance?

My TRD headers on the Tundra are stock and not coated. I live in a very NON Rusty environment. My headers were very very cheap. But i dont want to have to remove them to have them coated, not worth the effort for the gain.(to me)

The headers I had made for my MUSTANG (2" primary long tube-3 1/2" collector) I am going to have JET HOT COATED. It helps keep under hood temps down, promotes better scavenging and looks really cool. I am going to have the whole exh system in the mustang done that way.

I wanted the performace gain and heat disipation in my show car, the looks are just a bonus.

I dont think it would really matter in my everyday driver. My Tundra doesnt run hot, gets the same mileage it did stock and even if I wanted to look under the hood to see the headers, I cant, the trucks to high.
But thats me.
The ceramic coat may add performance and may make them last longer in some places due to weather and road conditions (salt/sand).
Will you feel the performance diff??? I cant answer that, sorry. But I doubt it.(unofficial opinion)My seat-o-the-butt meter cant distinguish 0-10 hp gains.

Yes header coatings work, its up to you if its worth the extra money.
