Dam this thread makes me wanna test out Mechanic shops in my area to see if their ass holes or not. Like going in and saying "Hey how much to change my oil and plugs?" I would love someone to tell me $800 because I use iridium plugs!

I have ran into the same problem Check Engine & Trac Off blinking. I also feel that the car is bugging and like there is not enough power. Also exhaust makes a different noise. Took it to the shop 3rd cylinder not working. It can't be a coil because there would be errors on other cylinders as well. I reset the codes and when I started the car everything was fine nothing came back on and the car was responding perfectly. I also know for the fact it can not be spark plugs because I did a tune up and changed all of them not too long ago.
Last summer i was getting check engine light with O2 sensors. I turned them off and then the engine light would come back on and then few days later it would turn off by itself. Since November I did not had any check engine lights coming back nor did i change my o2 sensors. Now we were getting some heavy rains and this happened. I took the cover checked sparks everything is fine. So do you think the problem is in O2 sensors and the time came to change them? Also my shop told me that O2 sensors go at about 2bills per piece and there is 2 of them that needs to be changed. If anyone changed them are there anybetter prices, if so can you post a link. Thanks in advance!

There is always the possibility of the car throwing one misfire code as i've seen it happen before. It doesn't nessesarily have to be related to the plug or ignition components, it could be a result of a fuel delivery issue such as a bad injector or even a compression problem with that cylinder(ie. bad valve seals, piston rings). Depending on the mileage of the vehicle, a fuel system cleaner or injector service can be helpful. One route i would take is to use an OBDII scanner and find out your fuel trims, that can also help point in which direction the problem lies.

As far as oxygen sensor codes, it sounds like you may have a heater malfunction because usually they start to go bad, code may clear for a few weeks, but it will eventually come back and stay on(that's if the code pertains to that). I don't think the O2 sensor is responsible for one cylinder misfire, but if it's a primary or upstream sensor then it may not help. If it is a post cat sensor then it will not effect performance at all, only give you a CEL. OEM Denso oxygen sensors have come down in price and you can pick up a universal(that requires soldering) for $70 or so. A direct plug and play are around $100 or slightly more, but no where near $200. Your best bet is to get the car scanned and post back all of the exact codes to take out all of the guess work.

What was the exact code you had before you erased it? Never heard of check cylinder code.

So I ran over a large puddle of water with my IS 300 2001 that's jacked down barely off the ground.... I had no other option. The car did stall or anything but ice I got out the trac off light started flashing and the check engine light came on. I reset the ecu and then took it to Autozone and the error message read P1349?? Can anyone tell me what's wrong with my car?

"Trac Off" can flash anytime the CEL is on, even if not traction control related. P1349 almost always means the oil control valve is clogged or the solenoid isn't shifting properly. There's a mesh filter that can become clogged. Use our custom Google box above and search P1349 OCV, there's probably a hundred or more threads on how to disassemble and test the oil control valve, which is responsible for the variable valve timing.

Not necessarily but performance, mpg, and the car overall won't act like it should. Usually when the oil control valve is plugged up pretty bad you will start to randomly misfire and throw P0300-P0306. The mesh filter tends to clog up so the engine can't make timing adjustments. There's many threads on this DTC.
