Whats up forum, back here again with a different Z :biggrin:

I just got my hands on another Z, 93' 2+2 and this one is actually stick. I just learned how to drive stick on this car as well
I realized i had not transferred the title under my name yet, but the check engine light flickers on and off while driving. When it first came on, it was about 20 minutes into my trip to my girlfriends house and stood on all the day. Then by the next morning, it was off up until about the night time. I ran ECU and got the codes 32 and 34. I did a fair amount of research and am aware that they have to do with the EGR and knock sensor. Knock sensor seems to be easier to try and fix, but i see a lot of vids relocating this sensor. I am a total NEWBIE with mechanics so i know very little of how to do certain things, but i wish to experiment with my own car and try to fix it myself. I saw other forums of people saying getting it done the right way which leads to pulling the plenum (dont know how). The EGR code has me a bit confused because i cant seem to located it. Do you guys have any advice for a beginner learner like myself and what i can TRY to do to fix these codes myself? I have buddies who are willing to help me out, but they are not much more knowledgeable than me. Any links to vids would help. Thanks!

In following what others have said about the knock sensors, I recommend doing the relocation. For your EGR, check all the vacuum hoses to start. The try the lifting the EGR valve trick while idling. That should help you figure out if you need to clean carbons or just replace a hose before getting into further diagnoses and replacement parts.
