I need help to verify proper EGR connections. Please take a look at pictures below and tell me how it is connected in your mx3. Here is picture of my EGR solenoid: http://i179.photobucket.com/albums/w297/sonsky_photos/mx3/egr_solenoid.jpg And here is my VICS shutter valve and EGR: http://i179.photob...

BADMIHAI, did you fix the problem or is it still taking so much gas?
I get pretty much the same numbers with my 95 RS (manual) and was wondering it there is something I can do.

I understand that turning ac on should cause rpm drop but as you said - after that it should compensate and go back. Mine does not go back. Engine idles at 800rpm, when I turn ac on it drops to 400 and stays there.

It turns out that the ac was overcharged and it was causing the clutch to engage and disengage. Adjusting pressure to the proper level fixed one problem.
I still have a question for u guys. Can someone check if the rpms drop on idle when u turn ac on?

94 base 4-cyl When I turn AC on and rev up to 2000 rpms the ac clutch goes back and forth. During the normal driving the ac turns on for 6 sec, then is off for another 4 sec - so the cycle repeats every 10 secs. This has impact on rpms I feel a slight increase/decrease of power during the switching....
