Replaced a leaky rear valve cover and put everything back together and got this code P1105 and a knock sensor code. it is also causing a rough idle. I never disconnected the sensor or had CEL 's before the job. I have checked for vacuum leaks 5 times and can't find anything. i have to drive it 8 hours tomorrow for a job interview on monday. Any suggestions?

 

Code: P1105 | Description: Manifold Absolute Pressure Switch

It's talking about the map solenoid.
