The other day I installed my cobb ap, Stage 1 93 with the cobb intake. It ran perfect that day, but the next day when I gave it gas it sputtered with no power, then the check engine light came on, read the code at it says cylinder misfire. Any Ideas?? I was thinking sparkplugs maybe.

I honestly don't know. I will datalog that on my way to work tomorrow. What should the fue pressure look like so I can learn these things. I'm still new to this platform and turbo cars in general. I don't want to blow anything up.
