Hello all, I have been told on a previous thread to clean the egr valve and the maf sensor, but the problem is I have search for both of these and I cant find anything on them. So could somebody please tell me how to clean both of these? Help would be greatly welcomed along with some pics and anything else to do for a tune up. Thank you!!

 

Hi, I just cleaned my MAF sensor and it was found in the air intake between the air filter and the inlet to the throttlebody.

This helped me:

As for the EGR valve, someone else is gonna have to tell you as I have yet to get to it for cleaning.

 

For EGR Cleaning...

THIS THREAD will help. I have an EGR valve in a box on my bench. Just do not have the time to work through a cleaning procedure.
