timing belt & p0300,p0301,p0303, p0305

my 03 sedona stopped running last week. Dealer replaced crank position sensor (it threw a code for CPS malfunction). Then they said timing belt tensionor was bad and belt had jumped a couple of teeth, so they replaced it. Now it idles rough, and I get codes for random misfire in cyl 1, 3, & 5. Did they get one of the cam sprokets off by one tooth in the 1,3,5 head?

its possible do you no if this is an interference engine (bends valves)??
if you can, do a compression test on all cylinders

good luck

I am pretty sure that this is an interference engine. Going back to the shop first thing Monday morning!
Thanks!
