So I’ve been dealing with little odds and ends issues with my focus. I had a hard start with a crazy rough idle that last 45 seconds then the car was gone the rest of the day. Fixed with plugs, IACV, and coil rebuild kit. I’m just curious I’m limited knowledge of these cars, but the car seems to have a severe dead spot in the peddle. I’m wondering if it has to do with the junk air intake system. Also I get this weird like metal on metal sound when the heat is on, car is in gear my foot is on the brake, or for a few brief seconds when I accelerate. Nothings loose, no heat shield bouncing around. Almost thought maybe something to do with the pulley system. Has anybody heard of issues like this with this car? Thanks, Billy.
