I got another tech question on Miataforumz.com that I can't answer and I am looking for guidance. Here it is:

Any ideas, my idle goes up and down (300 to 900) and have a marked hesitation around 2500 to 3500 along with high petrol consumption. ICV replaced with known good: plugs & leads new; TPS new; TB cleaned; EGR ok and cleaned. No codes!! Have ordered O2 sensor + temp sender (back of engine). This is a 2004 NBFL European spec (Etna model).

And hello there from France as I've just joined.

I told him to check for vacuum leaks and he indicates he can't find any. What else should we tell him? Please help me help him.

You can answer here and I'll relay the info

or if you want to help over there the link is: idle and hesitation - Miata Forumz - Mazda Miata Chat Forums
