Well, yes and no. The spark plugs, spark plug wires and distributor cap should be replaced every now and then, especially if there is misfiring, for example, when the weather has been wet outside.
And if that happens then your ODB II equipped car will turn on the CHECK ENGINE light.
Distributor caps...plug wires what is this 1980. I haven’t owned a car or truck with a distributor cap since 1990 and it was my old 1985 Jeep CJ. Every vehicle I have owned newer than 1995 has been coil on plug or CDI direct fired. Every European import I have owned was fully electronic ignition since the late 1980s points and caps went the way of the Dodo bird in the early 80s or before in Europe. My Saab had Trionic 8 cdi that used plasma over the plug caps as a sensor for knock,compression, boost psi, advancement, and cam position sensor. Volvo had a similar system with CDI and coil on plugs all 3 of my Volvos were and are COP from the 90s onwards. My Jaguar was pointless as was the Range Rover that replaced it. None of those vehicles ever got a “tune up” just oil filters, air filters, and new plugs most at 100k or 65k intervals for the turbos. Tune ups with points, caps, carbs and plug wires went away for European cars in the 80s ha points it would be like looking at a model T now a days.
Errrr.. Everyone knows what a timing light and dwell meter are, right? And, for extra points who can give the proper term for TDC! LOL!
A friend of mine had an E-Type Jag that was sure sweet but after going for his weekend cruising and hot ridding had to put in garage time to adjust the triple carbs. Every weekend. >p> In math terms;
(1 Evening Cussing Brit Cars + 3 Carbs) / 1 Jag = 1 Fun Weekend
