I know my muffler needs to be replaced due to a small home in it. When I get the vehicle up to around 100km/per hour it sometimes hesitates, almost like its missing or something. This only happens when I'm at or around 90-110 kilometers an hour. Is this because of the muffler? I've replaced the fuel filter, and also replaced the wire from the coil to distributor. It still does it occasionally, not sure what to make of it?! Any suggestions?

is there a check engine light on? check your air filter for a restriction also. when was the last time it was tuned up. it looks like you have a few miles on it
