My ECU is throwing the following codes, I don't hear any misfires but they are being detected none the less. Also I have a VAFC II on my car, but I belive that was installed a a week after the misfires started but I will pull it just to see what happens.
I have also replaced my wires and plugs since this all started.

So here are the codes
-P1259 VTEC System Malfunction
-P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
-P0300 Random/Multiple Cylinder Misfire Detected
-P0301 Cylinder 1 Misfire Detected
-P0302 Cylinder 2 Misfire Detected
-P0303 Cylinder 3 Misfire Detected

Thanks ahead of time for any help

Oh ya I have a 2001 Integra GSR

 

Bump

Anyone have any idea's?

 

First thing to do would probly be to get ur map sensor working, without it working ur ganna run really rich. As far as Vtec, check the solenoid, and check to make sure u got plenty of oil.
