I decided to install a aftermarket air filter, so I removed to OEM air filter and the air filter box and custom fit a pipe with a filter to the intake. However when I turned the car over the engine light came on.
I took it to auto zone and they read the code and it was a misfire in cylinder 2. How can I fix this?

My truck has problem starting and it will randomly die when idling or just stopped. Anyone experience similar problems?

I was wondering what are some good mods for the s2000? Cosmetic and performance?
