Hi thanks for your reply indeed I have and there are no codes. The problem has baffled me because I've never had these symptoms before. Is seems to me to be something with the fuel system but it doesn't make sense over 2500 rpm the problem disappears. It isn't so bad when it's cold have you known these symptoms with the fuel pressure regulator?

Hi I'm new to this site and need some help. I have a 2002 is200 with a misfire below 2500 revs anything over is pulls fine. I've given it a full service all the filters and all the oils. On occasion it fails to start on the first turn but starts up fine on the 2nd turn. Any help would very much appreciated thanks.
