ok here is the situation....i am having a problem with my sc auto...the car will idle slightly rough, right around 800rpm....when you press the gas pedal hard the tach goes up to around 2500-3000 rpms and then completely bogs down until you pull you foot off the pedal...but if you slowly press the pedal, you can run it all the way to 4000 rpms and then some, and hold it there and have not problem..there was a invoice from a garage that did a tune up(plugs,wires,air filter,fuel filter)back in oct 04, and on that paper it said that a back pressure test was done, and the car need new y pipe, and cats... well i changed that over the weekend and still same thing, i even ran the car for a few seconds with no exhaust hooked up and same thing...if anyone has some ideas, and can help me please let me know....
oh the car isn't throwing any check engine light..
