I am getting an Error Code 0206 and 0306. The car runs fine when cold but after it is warm and I start it, the car shakes at 35-40 mph.

I am trying to replace my coils and plugs. Problems is, I cannot move the copper pipe from the right side of the intake manifold. I have removed the two (8mm) screws on top but I cannot get it to pull out of the manifold. Once I get that moved I will be able to finish changing the plugs and coils.

Thanks for visiting 2CarPros. You'll need to disconnect the other end of the tube from the EGR valve. I'll post instructions below.

1. Disconnect and isolate negative battery cable at battery.
2. Remove EGR tube bolts (3) at exhaust gas recirculate (EGR) valve (2).
3. Remove EGR tube (4) from EGR valve (2).

Hello,

I have included in the diagrams down below diagnostic troubleshooting flowcharts for both DTC P0206 and P0306 as well as instructions for removing the coil on plugs from your engine. Please go through the diagnostic troubleshooting flowcharts to verify what is going on and then use the instructions for coil on plug removal to change out them and your spark plugs. I have also included information on the proper gap for your spark plugs.

Thanks,
Alex
