Sputtering 95 Blazer

sputtering 95 Blazer



We just bought an old Blazer with 187K miles on it. It ran fine for the first two weeks we owned it and then it began doing this curious sputtering thing when you slow down. It eventually stalls. I’m mechanically challenged however, when my wife brought it home the other day it sounded almost as if the muffler was doing strange things. Any ideas what it might be?

The basics are air filter gas filter check plugs and for good measure an oil and filter change.
