2000 Tundra O2 Sensors, Exhaust, Fuel Injectors Failing

[bermudatriangle]

Hello Guys,

I just turned 70k miles on my 2000 SR5 Ext Cab and I feel like pushing this truck off a cliff. Reliability is starting to eat at me, especially since my last Yoda had 220,000 miles on it when I sold it with few issues.

Major Maintenance to Date:

@10,000 Miles Power Steering Pump and Pulleys
-Warranty
@38,000 New Front Rotors (man they warp easy even when not towing)
-$500
@50,000 Miles 3x O2 Sensors
-Warranty
@60,000 Miles 2x O2 Sensors, Exhaust Manifold Cracked, Catalytic Converter Partially Destroyed
-Warranty
@62,000 Miles Resonator Pipe
- $180 (cost from friend)
@67,000 Miles 2x Upper O2 Sensors Replaced
-Warranty
@70,000 Miles Stalls at Stop Low RPM's Daily if not multiple times daily, idling around 400 rpms or so. Dealership wants to charge me $800 plus to do a fuel injector overhaul.

Ok.. Now to the current issue. My truck is now stalling only several thousand miles after getting the bank 0,1 O2 sensors replaced. Dealership is claiming toyota recommends I get the fuel injectors overhauled at a cool $800. I am in somewhat in an argument about the cost as I could replace the freaking things for a little more. I have a $100K mile (7 year) platinum warranty and the service writer is saying the overhaul is not covered. Has anyone else been having issues with the emissions on their truck? Man am I glad I bought the warranty now, but I shouldn't be having these issues so often. Toyota's reliability on this truck has been a major disappointment coming from a Toyota family.

Also, if anyone knows of a great auto repair shop in the North Seattle area, please let me know, as I am in search of alternatives.

Thanks

I had my rotors replaced in 01 after the recall, havent had a problem since and have had 1 o2 sensor go out on me. I just hit 60k on my 00 sr5 tundra

Didn't know there was a recall and my second set of rotors are trashed again.

I have a 2000 SR5 4x4. Replaced both front o2 sensors at 49k. I'm at 90k today and the only other thing I've had to do is replace the driver side window regulator. She runs great. I'm pretty happy.

I also had to replace two O2 sensors (under warranty). Put on brembo rotors with stock pads and now have no vibration. Had a problem with low idle and stalling after replacing leaking headers. I cleaned the throttle body and then had too high of an idle. Pulled the battery cable and everything reset back to normal.

There was never a recall, just a TSB.

[stratous]

Ok, I stand corrected, it was a TSB. They told me they put a new designed rotor and break pads on and have not had the problem again.

As far as I recall, the rotor was not different, you either just got a new one or had it lathed. The calipers were replaced with bigger models though.

[bermudatriangle]

Were the calipers a warranty item? If so, how do I find out if I am eligible because the dealership will try not to give me that info.

[freddie]

It was a TSB for break vibrations. The TSB expires with the original Toyota warranty so unless you are on record about complaining about brake problems during your 36,000 miles, you'll have very little luck getting the dealer to perform the TSB now.

What upsets me is that you the consumer never hears about the TSBs unless you go in for a problem. Is there a forum on here to alert us when new TSBs come out (people on here seem to be very knowledgable about these sort of things). It be really nice if there was some automated way to receive an email when a new TSB is produced for the Tundra.

Just had the same stalling problem the last two days. Today was so bad, it stalled at every stop light, or slowing down to turn. Replaced the air filter, (K&N was filthy!), and wiped down the throttle body as best I could with paper towels and break cleaner. Made a huge difference. Thanks TS, I would have never thought of doing this except I remembered reading in here somewhere.

Fuel injector either fail (causing a miss), stick open or leak (over riching the mixture or flooding a cylinder), the spry pattern deteriorates (causing a weak cylinder or miss fire) or can no longer flow properly (runs out of fuel at full throttle, poor idle, bad acceleration) I'm sure there are more symptoms. If you have none of these and just a bad O2 then I doute you have an injector problems. Still think you have an injector problem?
Google "fuel injector service" or check out this http://www.lindertech.com/reconinj.htm
Linders is a leader in fuel injection problem solving and can clean and flow check your injectors for a lot less money.

Did you ever get the idle speed problem resolved? My '01 has similar symptoms, except the warmer the weather, the lower the idle speed. I don't believe it could be injectors because it runs really well no matter how the idle speed is doing.

Would appreciate your posting an update.

Thanks!

If you dont run decent gas with good additives you will have fuel sysem problems. You might want to try cleaning the throttle body and PCV valve first. It is something you can do cheap. run a bottle of fuel injector cleaner through the tank.
Also for kicks disconnect the battery for c a couple minutes. The ECU has a memory and it could be corrupted. kill power to it and it goes into default mode and then learns as it goes over again.

Also might want to check ignition. I had a coil start to go bad and was a little rough at idle. when it went it idled low and had no power and the engine shook like crazy. replaced it and like a new engine. I didn't replace my O2 sensors until about 90k. It was out of warranty when I found out about it so had to pay for them myself. ouch.

Replaced the brake rotors once. Pads 2 times. 140 k on it now.
Also torgue is critical on alloy wheels. loosen the lug nuts and re-torque. I solved a lot of vibration problems by just re-torquing the wheels
I cleaned my throttle body and PCV valve the first time last weekend. I always run gas with additives like Chevron so it really wasn;t too bad though the idle speed did pick up about 100 rpm at first. since then has gone back to normal. the computer monitors and adjusts.

I am sure you have done it but also check for vacuum leaks. they can cause problems that drive you nuts.
