Well, ok, here's my deal. I just got my 240 about 4 weeks ago. It just got a new engine since the old engine had a crack in it. It also got a new clutch installed. About 2 weeks ago I was driving to school when the check engine light came on. I was gonna check the engine as soon as I got to school, but like 5 mins after the light came on, it turned off. I figured it was a fluke, but checked the fluids anyways. Now, today on my way back home, the light turns on again. It's really freaking me out cause I don't wanna spedn anymore money on repairs. However, about 5 minutes after it turned on, it turns off. I check the fluids once I get home and everything's in order. The car isnt overheating either. Any idea on what it could be?

 

This happened on my sisters car...it was the 02 sensors causing the check engine light to go on. It was also her CPS

 

CPS? So basically I just change my 02 sensor?

 

crank position sensor

This COULD be the problem, Get your ECU checked...find out what code is making the engine light come on

 

Alright, thanks a bunch. I'll go get it checked out once I have the chance. Could it be a serious problem though?

 

Since its going in and out...most likely not. But you never really know!
