So I tried the Drop Resistor Mod. and my ses light came on. Help!!!!! I pulled out the sensor that was closest to the drivers side front strut tower, and the car was staggering, then I took it for a spin and it would not go into 2nd gear, and now my ses light is on and I have never seen it on until I pulled the sesor. So now i unpluged the batterey and will start it up tomorrow to see if it comes off. Do you think I pulled the wrong thing. I didn't see any other things to pull. Please help!!!!!!! If I take it in will they fix it for free. i am still under the factory warantty.
