I was trying to figure out how to adjust the clutch cable last night. I removed a black plastic box going to the intake so I could get to the clutch cable. After I took the box out, I noticed it was only had one opening. I'm assuming this is a resonator for the intake. After I was done adjusting the clutch, I left the box out and plugged the hole in the TID. There aren't any problems with doing that on this car right?? I don't have a service manual, so I can only guess it's a resonator since it only has one opening. Hope someone knows what I'm talking about.
