2001 buick regal bogging down	Sign In

My 2001 buick regal is bogging down and not accelerating. It starts and runs but takes about 5 minutes to get up to 50 mph. At an idle, it sounds like it is being muffled when I give it gas. It seems to shift fine and the transmission fluid level is good. I checked the air filter and changed the fuel filter so far and there is no change in performance. Is there a module that could be bad or the catylatic converter possible stopped up? It just seems like it is not getting gas. Please help.

To add to dmac's suggestions and do check for exhaust restriction. Easy way - put a "T" on actual intake manifold vacuum so device it operated is still enabled and should read about 18 at idle and with no load, read again at about 2,000 RPM. Should read close to the same. If it drops at high idle it suggests an exhaust restriction. Sometimes it's not the converter but the muffler sometimes gets rusty inside - not so common but happens,

There are no lights on and everything seems to be free moving...linkage and brakes.
I did notice when I rev it up in park, it puts out some white smoke...
