ses light

[young_gun_ws6]

My ses light came on and my car started shaking really badly. I took it to auto zone and had them scan it. Got codes P0300, P0351, and P0355. So I replaced those two coils and the ses light is still on and I'm having the same problem. Any ideas on what I should try next?

how do the plugs look? also wires?

[young_gun_ws6]

The plugs and wires look good and they are conducting, but I have no idea how well. Is there any way to check how well they are conducting or should new plugs and wires be my next step.

To eliminate the coils you can move them to different cyls and see if the codes change. Doubt new ones would be bad though. More likely it's plugs/wires - shoot, try swapping those to different cyls.

sorry i know its off topic but will installing a cutout on the i pipe in 01 ss set off the check engine light?

[sunsetorangess]

thats a negative on the cutout, anyhow i would try swapping out the two plugs and wires from other cylinders and reset the comp and see what happens. Replacing random parts might not fix the problems and you will get mad for spending un needed cash.
