Okay Guy's and Girls I've got a problem that 's got me stumped... I have a 2000 Chebby Cathiter with a 2.2 and am getting absolutly no acceleration beyoud 20mph then it bogs out...let up on the accelerator and it slowly picks up again but not past 20 mph. The car has new plugs, new plug wires, new coil packs, air filter and oil change...When I bought the car, it has a rusted out flex pipe so I had a new one installed along with a new muffler and tail pipe and the car started to run crappy about a week after the flex pipe was corrected. My initial thought was that there was a back pressure build up and the catalytic converter was not functioning properly so i drilled out a section of pipe just in front of the converter to vent the back pressure but that did not help. I had one of the local Auto Zone employees plug in a scanner (check engine light is on) and it showed three things 1) car needs tune-up (car is completely tuned up to factory specs) or 2) car has vacuum leak (can't find one) . I'm at a complete loss here...Any ideas ???
