my 20i 5 cylender pinks between 2000 revs and 2200 revs at idle and driving.becoming a pain in the ass ave changed cap leads plugs rotar arm any ideas,also when i opened the cap the prongs were black,

are you using 95 ron or Super?

It does make a difference. If I run the 100 (2309cc 10v) on 95ron, it tends to pink a bit, but drives lovely and no pinking if using super unleaded.

the only petrol we have up here is 95 ron,no super stuff,lol going on a classic tour in 4 weeks down west of scotland so might try and fill the car with super stuff see wat diffrence it will do,

are you using OE plugs? i.e. iridium plugs (higher resistance) can cause much weirdness in older systems. arcing in the cap etc. when they draw a higher current/voltage.

well they'll be right if you got them there i'd think! as long as they are copper core.

it was just an idea.. things like titanium and iridium are designed for modern/higher voltage systems was all i was thinking. i'm probably barking up the wrong tree again...

i use bosch super 4 in mine but.. no expert!
