Usually 1 of 3 things. Ignition coil is bad, fuel injector is bad, or spark plug is badly worn. Mechanical damage can cause that too, but unless it's a really old car with a worn out engine, that's usually not the case.
How long should stitches be left in? The doctor who put them in will be able to best judge how long they need to be left in, but on average stitches on the face should be left in for 3-5 days, stitches on the bodâ¦y or scalp 7-10 days, and stitches on extremities 10-14 days.
If you have deep sutures, then you can remove the sutures in a few days. I would not recommend leaving them in longer than seven days as they risk leaving little pin point tracks. If you want to do everything to minimize the appearance of the scars, then I would also recommend using lasers afterwards.
