2004 ford expedition engine light on:(

[firefighter883]

It started yesterday, driving back home entire car vibrating and engine light flashing on and off.
Does anyone know what this could be? Does anyone have had this problem before?
Thanks in advance...

get it checked with a scanner, but i bet you anything its a COP going out. coil on plug. very common issue!

My guess is misfire due to COP or plug. Code will tell you which cylinder P030x with the x being the cylinder #.
