1982 1.3 Pinking - solve with fuel additives or su - RobT_75
Hello

I recently had my old Mk1 Fiesta tuned and it's running much smoother now - the ignition was very retarded and emissions were borderline apparently. However, I'm getting some mild pinking under acceleration and was wondering what is the best way to solve it. Do I get the ignition timing tweaked (as it's a late mk1 it's got electronic ignition) or shall I switch to super unleaded or an additive?

I don't use the car much so I'm not that worried about the extra cost of changing the fuel or using additive. I'd rather pay the extra than potentially knacker the engine long term!

Any thoughts/opinions greatly appreciated.

Many thanks
Rob

Has it been timed correctly for 95RON unleaded, or 97RON 4-star?

If the timing looks OK then it could be running a little rich.

I'm assuming the mechanic did it for 95RON, but I'll give him a call to see if he can remember.

Thanks,
Rob
