Misfire issue after installing intake

Vaune · 02-01-2019, 08:42 AM

Just recently installed a aftermarket intake and I'm getting all these codes. Does anyone have an idea what specifically could be the issue? I installed the intake yesterday afternoon and everything went well. This morning I woke up to start the car and let it warm up and I got a the drivetrain malfunction code. Then after that all the other codes came along. I just recently changed my plugs, so I'm not understanding the misfire issue.

Have you double checked you didn't knock/unplug any sensors?

That's what I'm doing now.

Found the issue. The air intake hose broke off. Does anyone know how much this will cost?

Do you mean the chargepipe to the throttle body? If so an aluminum aftermarket replacement will run you $200 or so
