been havin trouble with car lack of power. sometimes sulpha smell from exhaust .car playing up in slow moveing traffic ie kangarooing seemed to be worse with less fuel in tank so today took out fuel pump to check for split pipes or blocked filter and all seemed ok havent done pressure test yet but dosent seem to play up when driveing car at say 60 -70 mph no kangarooing or that so not convinced its fuel related was thinking maybe blocked cat has anybody had a blocked cat and what was your symptoms?also i read that if you take out the pre cat 02 sensor then drive car and drives ok ie more power that is a way to test for a failing cat anybody know if this is true car seems to be getting worse over the last few weeks and is really doing my head in so any ideas would be most welcome thanks guys 😃
