Hi Scotty. Had a big job done to the car. Had a burnt valve so got that changed along with the head gasket etc. It's all back together now. However I now have a very poor idle especially after a drive it hunts for a steady idle very quickly. And get slight popping noise from the exhaust changed the oil the spark plugs and coil pack. Cleaned throttle body. However the throttle body plate moves when at idle and not touching the gas pedal think that may be the issue. Do you have any ideas what to do thanks. It's a Mazda 6 1.8 petrol 165,000 miles. Thanks for any help. I'm from UK and iv just got to say I love watching your videos there brilliant and very interesting 👍
