just been out for a drive in my cav turbo and when i was about 20 miles from home my car developed a problem.
it sounds like its running on 3 cylinders (scooby style).
under acceleration its pinking like mad and the afr guage is going lean to stoich very quickly back and forth.
on idle it sounds fine but under load it sounds knackered(no power,pinking).
as its too late to be tinkering i checked the oil and coolant which are fine. What do i look for now? i'm worried.....
help, or i'll not sleep!!
