Add this post to My Notepad CEL code 32 and 34??? 12:50 PM 10/5/2008

Hello, i have a 240sx 1998 AT with 200,000 miles, the thing is that my CEL is on and i did the autodiagnosis and the ecu shows codes 32 and 34, which are EGR malfunctions and knock sensor, but the thing is i don't notice any malfunction, my mpg is the same (22 mpg) in the city, and i don't feel any change in the performance either (0-60) in 10 seconds as usual,

How can i fix this?

i would like to know if this is something i have to worried about? i cleared the codes from the ecu 3 times alredy but the keep showing again.

The EGR guide tube is more than likely clogged. Replace that and the EGR valve and you should be good to go. The knock sensor code isn't really anything to worry about as it happens all the time.
