In the past 500 miles or so, for some reason, the car has just "died" at either idle, or while almost stopped several times (maybe 4). it happened several different times while going slow over a slightly steep downhill drive (to avoid scraping the lip), also happened once while almost stopped on a very slight uphill grade.

Someone has mentioned a clutch switch...

Any thoughts on this? The car does start right back up. Has happened with full fuel and 1/4 tank, and a in between.

 

Mazda service bulletin for the ECU???

 

where is the idle at (rpm)? Do you have a lightweight flywheel? I had my car die on me coming to a stop when i have a lightweight flywheel on my MR2. Does it die violently? or a very slow slow death ??

idle is normal, about 760, 770.
stock flywheel.
the cut off is just like turning the car off. smooth, quick, just stops.

 

anyone?

 

not the clutch switch......if it was your car wouldnt start

 

Any mods on the car, or all stock?

 

yeah - engine mods:
cold air, SMIC, DP, midpipe, CB, PFS PMC

 

well, does not sound like the car is struggling to stay alive but just dies slowly...hum..how old is the fuel filter/pump/regulator/p-dampner?

So say if we just let the car idle, it will all of a sudden die? or is this coming to a stop, then it dies?

Danny

 

hasn't happened with it just sitting there (i don't think)
it was always while the car was almost stopped, or just at least moving (with the clutch in, or the clutch out)

 

Remove about 4 percent fuel from the idle and 2 percent from low throttle. Add 5degrees of timing at idle and 3 at low throttle. This is what I did to fix mine.

How much volts are you runing?
Also look to see if your puter is ground.

 

check the engine speed decelerator thingy in the manual. forgot teh real name

 

ok, thanks guys, i'll try all this out this weekend

 

Dashpot.

 

do you have a pfc or a computer because you can just set your idle higher and your car shouldn't kill anymore but if it does then you might have some problems.

 

how do you do this?? with the PFC commander??? If it is how can you do it specifically?? I'm having the same exact problem... my car has no problem when moving... its always just at idle.... please help.
