Andy's engine makes all kinds of odd surging noises while it's warming up, and the RMPs race. Sometimes at stop signs, the truck seems like it will stall. Tom and Ray suspect there might be two problems. The surging and stalling could be caused by a problem with the secondary throttle, and the other noises due to a bad timing chain.
