Hey guys I know you probably get this question all the time.
My check Engine light came on today for no apparent reason.
This problem happened about 8months ago. The dealer told me that the O2 sensors and knock sensor needed to be changed. I got it changed and no problems ever since.
Today. Those ***#$%^Hol guys at the dealership kept arguing with me that the "Stillen Filter" is the cause of my check engine light problems and they never even put the dam thing on the diag machine.

If possible can you guys give me some info on troubleshooting this. I know that there are codes to read from, but obtaining these codes and procedures will be a great help... I need to know the procedure in displaying the error codes and the translation on reading those codes.


Thanks....

 

The Check Engine Light is evidence that something is wrong. That
"something" may be any number of things, some major and some minor. It
might be nothing more than a loose fuel filler cap. The Engine Control
Module (the computer) detected a problem and turned on the Check Engine
Light. At the same time it stored one or more Diagnostic Trouble Codes.
Get someone to do a DTC readout for you. This is not a big deal, does not
require specialized "dealer only" test equipment, and should take less than
an hour. When you know the stored DTCs, you will have a fair idea of what
repairs are needed.

If you like to do your own "wrenching" you can do the DTC readout for
yourself. No special tools are required.

You will find instructions to do a DTC readout and reset
the Check Engine light at:

The DTC "translations" are found at:
