They changed the water pump and the timing belt and all the other belts 2 years ago. The tire pressure is fine, that's the first thing I checked.
I don't even know where to start. They changed all the fluids (engine, transmission, radiator, clutch, brake), they adjusted valves, checked the timing, replaced the spark plugs, did compression check, replaced the air filter, cleaned the engine bay. Since they did a lot of things I don't where to look. I checked for any hoses having holes and came up with nothing. Checked my pcv valve it's good, I replaced it half a year ago. I think they adjusted my idle because it sometimes it idles at 615-630rpm, but that could also be the valves. right?
