My SC just displayed the 'check' warning light this morning. I suspect it's because of my using K&N filter and airbox modification (I just made these air-intake modifications 2 weeks ago). Did you experience the same thing when you modified your SC intakes?

 

i do believe after installing the intake system the light came on that might be the reason. it also could be the O2 sensor going bad. i did however use a filter taken off of one of my previous cars, when the check engine light kept coming on i took the fiilter off and used the K&N recharging kit and it seems to be working MUCH better. it has only come on one time in the past two months. email me if you have any more questions about this or any other questions you might have at (drift180sxlsd@hotmail.com)
