I will check the dropping clutch trick in the morning.
From what i recall the rpm tact does not infact drop at all.. I will have to take it for a local spin and watch more closely to be sure. About 4 years ago i had the engine do the same kinda thing but just totaly shut off (never did the hesitation i get occasionally) and i remember the tact totally shutting down. At the time i brought to the mazda dealer and they diagnosed the Computer which they replaced. This is different in the sense that it will often hesitate.. Fuel pump was new about 2.5 years ago as well. filter is clean
I have been doing alot of reading in these useful forums as well with this engine and the problem so many have with the Ignitor modual and Coil. I am wondering if the possibility(and your opinion)of doing HEI mod using this set up http://forums.probetalk.com/showthread.php?t=1701206176
. Alot of info on this and can be done with adding an external coil or using the exsisting one. The Dist i have in the car was replaced about 1.5 years ago but im positiive it was remanafactured, and the price of that unit was silly.. and so many stories of them or intergrated parts dying.
I am very much leaning towards what you said babyhuey on the distrubuter since it seems to be the bane of so many mx 6 run problems. Would the rpmtach drop if theControl modwas toast or if the coil was toast? Or both? From what i can tell on the schematics the tact is fed the info from the coil?
I hate intermitent and sporatic problems. Again will check the stall thing tomorrow morning.
