^^^^Agreed.
Did you buy the car that way? It could be that your catalytic converter or 1 of 4 o2 sensors is bad.
Get it checked out, cus you gas mileage will drop dramatically.
Best of luck
EDIT: Just saw your other thread about you getting a short ram intake. The lights on the dash is caused by your aftermarket intake. You can switch it back to stock to see if the lights turn off. If so, then you will need to get a
SAFC-II to control your A/F ratio. If you dont want to get a SAFC-II, then buy an intake heat shield to block air to the intake. It could be that your MAF sensor is reading to much air. Causing your CEL/trac light to come on and flash. Our ECUs are tempermental, and if you dont control the signal to your ECU. You will have more problems than just a couple of lights.

pull the codes would b a good place to start. p0171 is a lean code prob to much oil on your air filter and damaged the MAF. flashing trac light is prob a totally different problem. take it to an autozone where they will pull codes for free and go from there.

The only thing you have to re-initialize is the clock and presets on your radio.
yaa so i just put my stock intake back on then unplugged the battery then plugged it back in. When i turned the car on the lights were gone.I drove around for almost 2 weeks with the aftermarket intake on before the lights came on....Do you think it would be a good idea to put the intake back on and try to do the whole battery thing in the case that the lights do come on again ?
By resetting the ECU by unplugging the battery for 15mins, will only tempararily turn it off, but will come right back. Auto parts store will not know how to fix it, thats why we are here to help you threw situations like this.

Hey i had the same problem. I put my injen intake in for about 2 weeks and the check engine light and trac kept blinking. Its just your intake because of the maf sensor thats all. Keep your after market intake in but take the sensor from your stock intake and hook it up to your after market intake and reset your battery and that should be it. Sorry im not more detailed cause my friend helped me. But yeah you have nothing major to worry about

When you disconnect the battery, you do not have to re-initialize your auto windows or sunroof. Whats the reason for you having to re-initialize your auto windows and sunroof functions, also, do you have an IS300?? ![Uhh...](https://www.clublexus.com/forums/images/smilies/1387914497.gif)
The only thing you have to re-initialize is the clock and presets on your radio.
If your Lights come back on, after installing the aftermarket intake, I would first go the cheap route and see if there is a heatshield of some sort. Here, try looking at this site... www.swiftracing.com Look at IS300 intakes and see the heat shield that I am talking about. If that doesnt work, then you will need to by a SAFC 2 as your piggyback. You will be able to control your A/F(air/fuel) ratio and get the ECU/trac light turned off.

This happen to me on the freeway.. I had really bad tires on the way to get new 1s it would give me bad vibration. It started flashing along with check VSC and it wouldn't shift it had to be done manually. So I pulled over and my intake sensor was loose it had came off. So I had tools I unplug the ground on my battery and re installed the sensor and tighten it down real good. Turned car back on and it never did it again.
