Scotty,thanks for the suggestions. I looked up the thread on proper knock sensor installation before replacing mine. I did it as recommended - angled it as shown and torqued to 17 ft/lbs. Will try the cat check, although I've doubts if I can do it as you described due to rusty nuts on flanges. Will give it a shot next weekend. Alex

Greetings, members. I have a similar problem with my 99' wagon. The car is running very rough, poor acceleration, difficulty on uphills - I need to downshift to lower gear (it's a 5-spd). The codes thrown out are 301-304 (misfiring on all 4 cylinders), 325 (knock sensor), 420 (inefficient catalytic converter). I just replaced the knock sensor - no change at all ($80 down the drain). What now I wonder. Converter is the most expensive item - will be the last thing I'd tackle. The car has 266K miles on it and has been OK until about three - four months ago when the drivability started to go down. Any recommendations are welcome. Thanks, Alex
