Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If you dropping out 4 cylinders do to the lack of 4 coils not firing then the first thing you need to do is make sure you have power to the coils on the power side with the key on the red power supply wire. If you have key on voltage on the power side then see if you are getting the ground switching signal from the PCM (computer ) to each coil. See the wiring diagram in the link below , copy and paste the link to your browser to open and view it. Check this and post back with the results and we can work from there. When you checked you oil pressure what where you reading?
