Help... Got 9 codes after changing..

my dads intake manifold... When I change my dads intake, the car started up but the idle was bad, it smelled alot of gas, had several missfires. SO decided to take it to vato zone to get it scanned and got 9 codes, I was like . Here they are:

P0102 - MAF or VAF Low input
P0136 - ????
P0156 - Bank 2 Sensor 2
P0401 - EGR Flow Insufficient
P0304 - Cylinder 4 missfire
P0308 - Cylinder 8........
P0174 - ????

That is what they gave me at vato zone. Do not know what are the other 2. I changed the plugs to new ones, same thing.. Have not changed cables in a while. I really do not know were to start.. Before I changed the intake, the car was running fine, just the except that it was leaking alot of AF into the plugs. So what do you guys think?!

Sounds like something is unplugged or some sensor went bad.

P0136 - Bank 1 Sensor 2 (Passenger Rear)
P0174 - System too Lean (Bank 2, Driver side)

Did you get the plug wires back on correctly? And all the vacuum lines?

double check your electrical connection...
make sure all your vacuum lines are hooked up...inspect for cracked tubing....
check connection at mass air flow

i just changed my intake 2 weeks ago...

did you unhook your spark plug wires...?check security,...look for a crossed spark plug wire..

with misfires codes...........ill bet you have a crossed wire...or a loose connection
