Basically when the car is cold it splutters like its cammed, unsure if it is or not. Under load in the morning it's hesitant like something is holding it back. Give it five, ten mins and it behaves itself but I can still feel the car vibrate. The car is stripped so it is prob more obvious. I've replaced the leads and plugs and its no better. It's not a real problem but something I want to sort. Engine sounds good and it pulls etc like no ones business. Anyway we plugged it in to a snap on diagnostic and it pointed to the rear O2 sensor being faulty. Now my understanding is that the second O2 sensor doesn't do much, it is still plugged in though. From my brief description do we think its O2 related? Car is decatted too. Cheers chaps. Oh and would it be worth swapping the sensors around?
