HelloCustomerand welcome to JA
Was the engine running better before the Cam replacement or is this a new problem?
Not to worry, you dont have anything on that engine that needs to be timmed other than the cam. Below is a photo of what the timming marks look like. Crank the engine arond until you can see the timming mark on the idler gear. If you pull #1 injector you can put a long screwdriver in the hole and know when number 1 is comming up. At this point you should be able to see the SRS sensor in through the hole (photo below).
Piston at TDC, idler gear mark at the Cam gear, and SRS sensor pin visible, you should be good to align the cam gear mark.
I will be here to help you more if you need it.
