So this morning I drove like 5 minutes and stopped to drop someone off and immediately following as I went to pull away the car started to shake violently like at somewhere around like 5-10hertz. It felt like a piston wasn't firing and the power dropped significantly and obviously i took the gas very easy. I drove it home because I was like half a mile from home and it was still running fine, of course the check engine light came up.

I checked the oil while i was at it and it was full and clean, the exposed belts were all in place and tensioned. I haven't gotten around to checking the wiring to check for loose connections.

I am guessing either like a spark plug or wire connection or something that is dealing with the firing sequence. Any thoughts/suggestions?

 

Its a coil. Trust me.
