Hi all several months ago I rather idiotically half-filled my 306XSi with diesel. OOPS. Ling story, no need to go there, etc. I managed to top up the tank with petrol & limp home, topping up as I went to keep the Diesel percentage as low as possible.
Over the last month or two I've noticed the engine being a bit erratic at low revs. Well ... it's not exaclty the engine, but the ride is certainly jerky if I take my foot off the accelerator on lower gears.
The car has done 100,000 miles and I'm guessing that a new Catalytic Converter may be required soon. Might this explain what I'm experiencing, and might my diesel c*ck-up have brought on the problem or made it worse? Is there anything I can do to clean the Cat or similar?
Thanks for your thoughts Jon N
