hey zilvians
i got a question for tech guys out there, i have a stock ka24de with 131k and a 3 inch catback exhaust. The car was running good, then i took out the silencer to my exhaust to test it out. When i drove it around, the CHECK ENGINE LIGHT comes on and i was like O.o I checked the light out, and it gave me "knock sensor (34)" and "egr malfunction(32)" code and its been on since even with silencer back on. My question is
Oh, the car is running okay, i dont feel any difference in performance, i think.
-Are these codes something i should really consider fixing or getting it checked out? will it affect my car in performance and safety wise?
-What do you guys suggest or what would you do?
Appreciate the help
