I removed the air box on my spark Ls and installed a cone in place. It would be considered a short ram intake, maf sensor still in same place. Ever since my car has been having been having issues starting. I'll have to go back and forth for 5-10 min before it actually starts. When it rains, sometimes it'll shut off while idling in neutral. This has been happening for a few weeks now and is getting to the point where it happens everyday. Any opinions on what could be happening?
