I have a 2002 international 3400 (t444e) bus and it starts good, idels good, it just does not want to move when it is put into gear and the throttle is pushed. It has a little gray smoke out the exhaust. Oil is new, fuel filters changed. This problems has been getting worse over the past month. I am thinking cam sensor. Help please.
No codes stored. Checking on it, I think the problem is the brakes. It has good throttle response with out trying to move it. I was told the air pressure is low, but I do not know how low. The park brake may still be ingauged. Thanks for the reply.
