i have a 2008 suzuki forenza i just change the cylinder head cause i had a timing belt issue. so that was changed along with the tensioner and guides. i have also changed the plugs and wires, cam position sensor, power pack. i have been getting the missfire codes and also P2110, P2106 and P161B. i need some help finding out which direction to go. i have not found any thing online as of yet. i spoke with some friends and they are stumped. does anyone have any ideas.
