Cuts out when idling. i have tried adjusting the timing with no effect. Help!!!

when you were working near distributor you might have pulled out/ or bent the vacuum pipes.

have the carby overhauled as you may have dirt/water in the idle circuit . Adjust the idle mixture screw a bit. Adjust the automatic choke to come on more at idle.

The O2 Sensor only effects the idle to a very small degree

A worn sensor is one that switches slowly & thus effects
the PCM,s abiltiy to correctly adjust fuel injector pulse
width or timing.

Try to check the throttle position sensor, or idle control valve is equipped

That engine runs at low speed, starts and idles on the center carb only. first make sure the carbs are synchronized so the front and rear ones are fully closed at idle, then adjust idle speed and mixture on the center carb. Sweet ride by the way, if you get tired of working on it and want to get rid of it I will take it. LOL

dealer only its a fly by wire ,be prepared for bill with a meal

Shelley,
This gentleman has written a pretty good guide for checking and adjusting your ignition timing and idle - http://www.mx5oc.co.uk/forum/forums/t/208.aspx
Try adjusting your idle - I wouldn't be surprised if this is not your problem (or only problem). If the idle is still drooping (or cutting out), you might like to think about checking, cleaning or replacing your air filter, cleaning your throttle body and possibly checking the correct function of your two clutch switches which can all cause similar problems.
The clutch switch problem is becoming somewhat more common now - have you tried idling the car without A/C? Then experiment with doing the same with the clutch depressed and then with the clutch depressed and a gear selected...if one of these combinations stops your idle problem, you'll probably find one of the clutch switches is dead. The purpose of the switches and the reason for the problem is a little complicated - if this turns out to be the case, reply and I'll try to explain it properly.

Yes, the first thing you should do is have the timing checked and adjusted. If the problem persist you may have to have someone adjust your idle speed.
