****PLEASE HELP****

I have a 97 240sx with about 130k on the motor.
The car is completely stock and runs fine.

Recently the "Check Engine Light" came on and I'm not sure what it is...:confused:

I was thinking it could be a sensor but not sure which?
O2, Crank position, CAM position sensors..:confused:

How much does the O2, crank, cam position sensors cost $$$ ?
I'm thinking about changing all of them just to be safe..

What do you guys think...??

****PLEASE HELP****

Thanks in advance!!!

Pull the trouble code(s).

We are not the dealer. Call your dealer and ask for prices.

I think you need to get an OBD-II scanner and pull the codes. Go on from there.
