Use an inductive timing light to check the regularity of spark for each plug. If you are truly missing spark randomly, try the crank and cam sensors.

You may also want to check compression. A blown head gasket will do that.

Yeah, just got back in from playing with it and no luck. I was trying to check for vacuum leaks.

The CEL actually was flashing before it stayed on constantly and you can feel the mis-firing while driving.

All this started when my Intake bypass hose disconnected fron the intake manifold, I figured I burnt out injectors or something from the car running too lean but now i know thats not the problem anymore.

check your ignition system. spark plugs and wires and check the coil pack. my car did that also. the shop i took it to replaced the plugs but it didnt fix it. so check the wires and coil pack
