I know a local spot in Long Island to get the Bilstein and runrite done Nick.. Other locals had this service done and can attest to the results.. You can try CRC MAF cleaner (use this only) to clean the gunk off.. If this fails then you will need to replace the o2 sensors.. Good luck..

Seafoam claims that their product will not harm O2 sensors. I have personally ran seafoam through the intake manifold of around a dozen cars and I have never had an O2 problem arise. Im not too familiar with the lexus computer and cel cycle but you would foul your spark plugs before anything else. You may have had a misfire due to a fouled spark plug. Just my opinion and experience.

Sounds like carbon build-up on the 02 sensors. Seafoam I know a local spot in Long Island to get the Bilstein and runrite done Nick..

I shouldn't have used this stuff. So your saying I should clean the O2 sensors with the MAF cleaner? All of them? How many do we have? I know 2 of them are located on the Y-Pipe (one for each side).
Also, for the last 1+ year my car has always gotten poor gas mileage; could my O2 sensors have been on their last leg and just dropped dead because of this cleaning?
If it did foul my park plugs then that sucks too because I have my Torque Maters in there and @ $12.50/ea this is getting pretty expensive (and stupid). What would fouled spark plugs look like? Would/could cleaning them do the trick? Sorry for all the questions Sean. My dad always says if it ain't broke don't fix it...I am starting to realize I should take on this philosophy.
I had some extra time on my hands and this is what happens.

Seafoam has fouled a few 02 sensors, but to bump up MPG's..New 02 sensors and cleaning the MAF is a good idea..
If you want get some Seafoam deep creep and clean out the gunk in the throttle body as well
..Change your oil in less than 250 miles BTW

2nd Autozone/Advance Auto. I wouldn't replace the spark plugs, sometimes the plugs will burn off the carbon that caused the misfire in the first place. Let us know what you find out. You have time to hit up Autozone today?

BTW, IF I have to replace my O2 sensors should I replace all of them at the same time? What I mean is, if I replace the problematic one (if there is a problem with the O2) will the others go shortly thereafter? Do they have similar life expectancies? How much are they (a good deal)?

Some people say your other o2's will go out soon after but I disagree, just change the one that's bad if that's the case. I ran the universal bosch o2 sensor in my audi s4 (twin turbo) and they were just fine and lasted just as long as the oem ones. Around $65 compared to $150. Cant beat it in my opinion.

Universal Bosch's are about 50 I think or so..

There's a way to test 02 sensors if I remember from my messing around with Honda dayz

Lexus Test Driver
The CRC MAF cleaner works well on cleaning 02 sensors and of course MAF sensors but find out what the code is first. Personally I stick with Denso 02 sensors after several issues with bosch sensors in the past on other vehicles... probably just my luck more than anything else but thats just my preference. I would also only change the bad sensor if one is actually bad. I've used seafoam on several vehicles before (mazda 626, I30, chevy blazer) and I've never tripped a CEL code from doing so... unless of course I forgot to reconnect a hose or something... I have however had Lucas injector cleaner run on my 626 and Catera.. in both cases I had a CEL light almost immediately from bad precat sensors... most likely a coincidence but just sharing my experience. Get those codes scanned and let us know what comes up... and if DaShocker revisits this thread let me know where I can get that bilstein treatment done, for some reason I can't send PM's from my work computer.
