Hey Scotty.. i have a ford focus Mk1 HB 2005 with 1.6L DOHC engine. its already 258000KM. Issue that i'm facing is, at highway speeds suddenly car starts loosing speed and power without changing the accelerator position.(straight plain flat rods) its feels like applying gently brake. also a burning oil smell when its happening. sometime back firing if i kept the throttle same position. its goes back to normal when i let go the throttle. it happens about 2-3 time between 30 KMs.
please check out the video. as you can see its speeding down without any changes to the accelerator position.
