set off the other day to find my punto (mk1 60s) jerked in low revs for 1st and 2nd gear. as soon as it got up to speed it was fine.
changed my plugs and HT leads (after some advice from a passing mechanic) and it is still rough.
i've been told it could be numerous things such as:
collapsed CAT
injectors
coils
the thing thats worried me is that i have a seperate breather as i've fitted a K&N, when i rev the engine white smoke comes from the breather! the gas smells like exhaust fumes, when i listen to the exhaust the car doesn't seem to be in rhythm, its like its running 3/4 instead of 4/4. i think i have lost a little coolant but i've done 70 miles since the first time i noticed the problem.
any advice, experiance - thanks in advance
