Any advice appreciated...
Have a '94 M CO: %vol - 0.00 HC: ppm vol - 013 CO2: &vol - 13.39 O2: %vol - 2.48 Lambda: 1.131
Tester said lambda readings failed test. Car was idling rough and have since replaced the Idle Air Control Valve which has smoothed that out.
Exhaust had 2 small 'blows' & have since sorted that out.
Have just serviced the car (although it was last seviced just 8,000 miles ago).
Lookng for any other suggestions, from gas tester readings, as to any other electronics that may need replaced.
I don't have any local diagnostic centres, although there is a Ford centre about 25 miles away which I'll go to as a last resort...
TIA.
