Pinking

I drive a 1993 190e 1.8 european version and I seem to have a lot of pinking when driving at different speeds, any ideas?<br> Also sometimes after long journeys with the a/c on, the engine refuses to shut off even though I have turned the key off.

if the engine is running on after you turn off ignition it is definately timing try the distributor i know you can turn that backwards and forwards just a fraction to retard and advance the timing without touching the timing chain i used to do it on my peugout 309gti a few years back dont know if its same with the mercs though<br>

Re: Three Types!

I am using original merc plugs and there is no carbon on valves. I have purged the injectors and done a complete tune up but the problem is still there. The garage also think I might have filled up with contaminated fuel, so my next step is to drain all the fuel and fill up again. <br> Has anyone of you had problems with your cat convertor? if so what are the symptons?
