My car sounds like its misfiring and engine shakes really bad. Headgaskets are fairly new replaced 6months ago. The coolant has no oil in it oil is brand new. Possible a bad fuel pump aswell?

Any codes?
When did this start?
More so hot or cold?
Does it get better or worse with rpm?
Which engine?
Why do you suspect camshaft sensor?
Could be as simple as a spark cable came off.
Please tell more.

I had my mechanic scan it and it said cam sensors, we replaced those then looked at the timing chain and it was lose/streched. OS there anyway to replace the chain without pulling the engine in a 2008 G6 Base 2.4L
