I recently installed the K&N Typhoon into my '01 IS300. After 40 miles, the Malfunction Light came on ...... I took out the MAF sensor, and it was dirty ... I cleaned it, then reset the ECU.
The car was fine ............ after 195 miles now ........ the light has returned !!
I have taken out the MAF sensor, but it is clean !
Now ........ I start the car up, and after 3 seconds, the VSC and TRC OFF light comes on !!!!
What could it be?
Help! :cries:
