CEL and check VSC WITHOUT headers !
Alright boys and girls, here is a new one. My car has been idling a little ruff recently and getting some hesitation in my F recently when taking off from a stop light. At lunch today the car was idling ruff and hesitating, but when I took off at the end of the day the VSC CEL lights came on the dash and the car went into limp mode ( like driving in snow mode ). I thought this happened usually with headers but I don't have headers. Just a Joe Z exhaust .
Was wondering what you guys think this might be from ??? O2 sensors, MAF sensor???
Anyone have this happen to them WITHOUT headers?
I immediately called the dealer and got her in this evening. Was just trying to pick some brains as to what the source may be. They should have some more info for me in the morning .
Thanks so much guys

Another question.....Looks like the O2 sensors are cheap as hell. Are they the same right and left or is there a different part number for the right and left sides?? Found the Denso parts on Amazon . Might change both out since they are less than $70.

Rather than guessing and using the shotgun approach. Why not invest in a code reader and read the code? Maybe it is the o2 sensors, but code readers are really not that expensive and a visit to the dealer armed with that information may actually be of some help.
And I don't know about you, but $70 bux is a lot of money to me!
And BTW, maybe it's just me, but I find your signature pic to be in extremely bad taste. Yes, I know the Eddy Murphy origin, but to me, it just rubs me the wrong way especially in this day and age.

Lou, as far as the signature pic, Lexual Chocolate was my nick name at the local dealership because my plate is LEXUAL1. I am close with my SA and techs so we all laugh at the plate. I also have dark skin, therefore Lexual Chocolate. If it offends you then it may offend others as well so I will swap it out. Sorry to have offended anyone. Much love to my Lexus family

could be a bad wheel bearing/speed sensor /sensor wire. just throwing some stuff out there.
investing in a nice code reader is a good idea. mine has come in handy and im usually always the first to be called when friends have problems.

Right on ! I would have assumed that these code readers were very expensive units. As far as my current situation ( she is already at the dealership ) I was thinking of maybe ordering them preemptively . I have done some leg work and it looks like the most common culprit would be the sensors, sensor connection, or an exhaust leak before the location of the sensors.
They did the labor for the exhaust . I am hoping its just a loose connection or minor leak but they way the car has been idling and hesitating intermittantly I would assume its a sensor.
Its like gamble the $138 on the fact that the dealer could charge me $270 more if its a sensor.
Also if it is a sensor would you guys change just one or is it advisable to replace both ??
Thanks for the replies guys. I appreciate your time and attention

I'm not offended at all my lexual chocolate, in fact I thought it was hilarious. Coming to America is one of my all time favorites. I may be a tall goofy blonde and pasty guy but I know a great movie when I see one. Don't worry too much about offending people as many people are just too thin skinned these days

Could also easily be an $8 crush gasket (x2) at the manifold to x-pipe flanges..
Remember you have a good amount of race weekends locked in.. So if those bolts get loose and/or the gaskets begin to disintegrate due to excessive heating & cooling cycles.. That will easily throw a code for a bad reading on the O2 sensor..
The way to find the leak is to cup their hand around the flanges while someone is revving...
And for sure I wouldn't replace a sensor unless it was absolutely necessary showing bad or damaged. Also, if those sensor wires are wound up or twisted on reinstall, that too can cause the sensor to foul or go into low voltage reading..
If they need anymore technical support, I know you still have my hotline number
