Ive had occassional cylinder misfires (diagnosed by my Sealey EOBD) over the last couple of months. Engine hesitates for about 2 secs, warning appears and then engine runs fine. Car has done 115k but well looked after. I guess ignition coils need replacing. However does a good spray of WD40 normally solve the problem?? Is it ever worth just replacing one or should i do the 4?? Any good sources for good value replacements??
Thanks
