I bought a 2001 Taurus a little over a year ago. A couple months ago I started noticing that the acceleration was getting so bad that I had use my gas pedal on hills and that a burning oil smell was coming from my car. I took it to my dealership and they found that I blew my oil pan gasket, and that the oil has worked its way through the exhaust system. So they replaced the gasket and cleaned out the exhaust system. Now just a month later, I am finding that my acceleration is horrible and that the burning smell is still present off and on. So I take it back to the dealership and they find that the oil filter needs to be replaced, which of course should have been replaced when I got my oil changed. I am pretty sure the smell has gone away but the acceleration is still lacking. Does anybody had this problem? Or does anyone know if this could indicate a larger problem?

Not totally clear as to why if your oil pan gasket was leaking, it got into your exhaust system. And how is it that you clean an exhaust system. I have never heard of such a service. It sound like a real money maker. :angryfire . If you had foreign material like oil going into your exhaust system there is a chance that it could have contaminated your convertors. If they got plugged up this would give an acceleration problem. :sunglasse
