2000 S320 Losing Power
 

Hey all,

I'm having problems with a 2000 S320 which loses power even at full acceleration. The engine misfires and there's downshifting in the gears.I have diagnosed the car but there are no fault codes. I suspect that the catalysts may be blocked. Is there an easy way to identify this problem?! Also, has anyone got any other suggestions...


Thanks
