Hall to all I just bought my first own car, a MX 5 NB FL in Pure White from 2001. I got it ultra cheap and I’m ready to do a lot of things on the car. The usual thing like a sleeper and underfloor is on. Now, however, I have a slightly smooth, catchy noise next to the engine noise in the low speed range and idle. It can only be heard in the interior. When the hood is open, I didn’t notice anything. Oil level is good. The engine also runs clean (without knowing too many MX5 engines now), linear gas intake, speedometer 200km/h at 6000 rpm was also quite easy. I know, remote diagnosis will hardly be possible. Will show the engine to someone soon but maybe there is a typical source of error. I tried to record this once by mobile video (difficult because the noise is very quiet). I load up however. Best regards.
