I just swapped in a b16 into my ef and rite now its running like crap. It feels as if the firing order is all messed up, but its not. The thing is that when the engine is still cold it runs fine but as it gets warmer it starts to feel like **** and then the check engine light comes on. It throws the knock sensor code. please help me

 

Did you plug in the knock sensor?

 

rear of the block, under the intake manifold. single wire. its one of the wires you had to "add" for the 4 wire b16 swap.
