Spark plug light intermittently comes on during hard driving
My 156 drives really well, just sometimes during a long drive, when driving hard in 2nd gear, the spark plug light pops on for about a second or 2 then dissapears, and doesn't appear again until another long trip with hard driving.
I can't be sure when the plugs were last changed, and I have bought a set of NGK platinum's for her. I'm just wondering if anyone has any advice other than the obvious... that they need to be changed.
The only reason I'm iffy about changing them is that the car had alot of work done before i bought it at around 85,000 Km's
cam belt, tensioner's, water pump, radiator..
If I take the front plug cover off and pull out a plug, will I be able to tell its age and functionality from looking at it??
