Misfire #4 welp took it to a "mercedes shop" not the dealer, they said it was a leaky injector and plug and advised me to change coil too even though it tested good when they swapped position in engine bay, is this fair price ? Or should I take car somewhere else?

I mean, it's very likely only one of those things is a symptom (the fuel injector). If it's not high mileage I'd just do that.

@adi-benz WELP YOUR RIGHT they said the the injector was leaking and fouled the plug so 1700 bucks later they changed the injector and 1 spark plug
