Hoping someone can help me out here. I have a 2003 allroad, 2.7t. It has been driving and operating perfectly, no issues. I suspected a plugged heater core because id get no heat in the cab unless driving down the highway. So I pulled it into my garage, disconnected battery and pulled out the core and put everything back together.

After re-connecting the battery, got a code saying the throttle body wouldn't adapt, after several attempts I just replaced the throttle body, and cleared the code, and it seems to adapt fine, code never returned. Now my check engine light is blinking, which I know means a misfire, but the car won't even fire. Cranks but no start. There are no codes displaying when I check my scanner, and I'm at a bit of a loss. Any suggestions?
