Is there a difference between the computers in 5-speed and Automatic mass air cars? I did a mass air conversion, and went to a local hot rod store to purchase the A9L computer. I got it and installed it and everything, and it runs good, but recently we pulled a code for the 'neutral drive switch', which leads me to believe its for an automatic. (my car is 5-speed) Like I said, everything runs fine, but I was wondering if its the right computer. Any ideas?
