engine running rich, likely misfiring especially noticeable while idling, talked to a subaru mech, and he suggested plugs/wires/coilpack, but wanted 300$ to do it, as apparently the engine must be removed to do so. True or false? (plllleeeeease be false). i paid 600$ for the car, and i didnt think id have to spend 300$ so soon, and if i DO have to take the motor out, im gonna wait till i get back home, and my friend can prob do it for 1/2 what suby wants
