Timing belt problems
It was time to replace the timing belt on my 1998 Ranger 2.5 4 cyl. it was running rough and back firing. when the harmonic balancer was removed the aluminum sprocket on the back had some teeth that had broken off. A used balancer was purchased the timing belt was replaced. Engine still runs rough and engine code " camshaft sensor". Long story short: crankshaft sensor, camshaft sensor,another balancer (guaranteed to be correct),and ecm were replaced with no improvements. I re-checked all the timing marks they are spot on. Any ideas?
