Hi all,
Our old 850 estate has developed a sight misfire. Seems to be worse when under load at high "ish" gears and light load i.e. say 40 MPH on the flat in say 4th gear there is a slight hesitation/misfire under acceleration. Under harder acceleration and at faster engine RPM's all seems fine. Starts first time.
Someone said the other day that these engines were very fussy re the spark plugs which are Bosch single electrode ones, and these look fine just a slight tan/grey colour no soot or fouling at all. Distributor rotor arm are all clean, no signs of tracking. Car is 1996 vintage done
124 K miles.Anyone any ideas?..
cheers
