2003 V70 Check Engine
Check engine light came on - message try slow down or shift up. Took to shop yesterday, told second cylinder misfire needs either coil or spark plug. Can't do work as owner is not in and they're on vacation for two weeks beginning today. Shop reset so message is no longer appearing. Said okay to drive car for two weeks
Am concerned and wondering how another shop will determine what's wrong if the error message is no longer appearing.
Also noise from engine - first told it's air conditioner compressor then told it's power steering pump. I think power steering fluid is leaking.
What should I do?
