I'm the owner of a '97 ka which is pinking slightly.Local garage states it could be due to a build up of carbon.As they couldn't be sure about this without taking the head off, they suggested I try something like Redex poured into each cylinder.Is it worth giving this a try,and whats the best product to use and how.
ps. diagnostic check showed no problems.

Yes. Try some spray de coker. Holts do one, so do others. It worked for me. Follow instructions on can. Then drive at 95 on the motorway for a bit. If it does not work, retard the ignition a little. That will work.

Use some injection cleaner in 10 lts of Shell Optimax fuel and run on a quite motorway at 70 mph. What fuel have you been using ??? Regards Peter

Not sure where to get the holts stuff Cyd.I've just being using normal unleaded until recently Peter,then tried Optimax,which I must admit helps,but still does not eliminate the pinking completely.
