I recently had the timing chain replace. I changed the ignition coils in cylinder 1 and 4, I also change the spark plugs. The car was running fine the from no where it the check engine light came on and it started to run real bad. It would stall when I came to a stop, it is also very very slow at take off. I heard clanking coming from the engine so I stopped at Advance Auto and the pulled the following codes.P0350 Ignition Coil Primary/secondary malfunction. P0340 Camshaft Position Sensor A - Bank 1. P1151 Manfacurer Conrl Fuel Air metering. I need an ideal of where to start. Thanks
