I went yesterday to my local Dealer to have them diag. the car and these are the results.

*/** should be numbers here

And this is what they wrote:

MIL TECH FOUND RACING EMC INSTALLED IN VEH.-COMP. INFO GIVES HARD CODES FOR KNOCK SENSOR AN EGR SENSORS- OEM ECM HAS TO BE INSTALLED FOR REPAIR.

When i went back they told me about the racing ECU and that nothing can be fixed w/o the OEM ECU i just and told them i'll put it back before i'll come back. I also found out that there's 4 or 5 EGR sensors and that they have to know exactly witch one is failing in order to be replace and one of thech told me that they were out.

Now i'm trying to get a OEM ECU to install and fix any problems if there's any and send my ECU back to JWT to have check out.

My factory service manual is for a '99 Maxima and the '99 EGR setup is different from earlier 4Gen cars. On the '99 there is only one sensor with EGR in the name and it is the EGR Temperature Sensor. Perhaps your dealer can give you more specific information about "4 or 5 EGR sensors" as to their name and location.
