Infiniti I30 Service Engine Soon

[frankfort]

The Service Engine Soon light of my Infiniti I30 2001 came on about a month ago. Just last weekend I cleaned MAF (followed instructions found in this forum), throttle, and changed spark plugs & air filter. The SES light went off for almost two days and it came back on again. Can someone give me advise what else would i need to fix?

Thanks in advance.

Go to AutoZone and they can hook up an OBD II scanner for free, Once you get the SES Code, you will have an idea what the problem is. You can also use the procedure in this forum (I30/35-Maxima FAQ) to retrieve the SES code as well as the meaning of each code.

Is the car having any performance problems besides the check engine light?
