Car idles rough also runs rough in overdrive. Problem started after a oil change???? weird..Catalyst was stopped up had to punch a hole in it to get it to run. Took it to muffler shop and had catalyst eliminated. Car runs better but still idles rough and at steady speeds runs rough. Runs so rough it makes engine shake in engine compartment..thought it was the drive shaft when driving but it also does it in park. I changed the plugs and wires...removed egr valve and cleaned (dont know much about them)....what you think?? fuel filter??? muffler?? ????? thanks

Changed fuel filter, o2 sensor, and pcv valve, cleaned throttle body today..still idles rough..runs good at acceration but at steady speeds car struggles..also noticed when stopping on a incline and taking off car really struggles...vehicle sat up for probably a year before i got it. Already ran several tanks of gas thru it...car only has 49000 original miles Any more ideas
