car is idling rough and misfiring. I took it into my mechanic and he did an engine compression test.. compression was fine but detected a faulty spark plug and wire.. replaced them and checked ignition coil.. did a pro vac on the injectors, but engine continued to idle and misfire. now he tells me that he thinks one of the injectors not working properly and wants to open up engine and check injectors.
seems to me he doing alot of quess work on my vechile and taking me for a ride.
any suggestions??
