I have a 1996 VW GTI (golf) Its spark plugs and wires were last changed at 122k miles and its now at about 158k. Over the past three years its had a few miss-fires and recently its been hesitating in rainy weather. What would cause the plugs and wires to be so heavily affected by the wet weather? Is around 35k miles a normal life expectancy for plugs and wires?
The car is driven regularly under fairly good conditions, I don't redline the engine or shift rough, the oil gets changed on time, although it doesn't have a garage to live in... it has to be parked out in the open unfortunately.
Thanks!
Changing spark plugs and wires - frequency?
The life of spark plug and wires are dependent of the quality of the replacement product- if the plugs are platinum the recommended service interval is 100k non platinum is usually right around 50k- you may have other problems unless this is a regular thing for VW. I know wet weather drivability problems can be caused by bad wires but could also be caused by a bad baro sensor or water leaks dripping on electrical components.
