Hey everyone! I have a '97 Merc Sable with a vulcan engine, and it's running slower than a 4-cyl mustang. When I bought it last fall, it had some punch to it when I went wide-open throttle, but it's not doing anything now. It had to sit over the winter due to some suspension work that needed to be done, I'm not sure if this impacts anything. I've changed the oil & the air filter, and just changed the fuel filter (it looked like it's the origional) and still nothing. I plugged it into the reader, and no codes came up. I'm going to try some fuel-injector cleaner next. Has this happened to anyone before? 145 hp and 180 ft-lbf should accomplish SOMETHING. Any help would be appreciated.
