Question about 1994 Mazda 626
'94 Mazda 626, 4 cyl., Manual trans. Runs fine at low speeds or idle.
After driving for approx 30 - 40 miles when cold, it stalls. It will restart. Initially, it started as a miss, and has progressed to a stall. When I pop the clutch to restart, it backfires through the exaust. It has progressed to the point of not wanting to restart after stalling. I have it in the shop now, and the mech has it running. It is running fine, and hasn't stalled.
It seems to only stall at highway speeds.
I would start by checking the spark plugs and leads. if that ok i would think there is a problem with the dispack that the spark plug leads fit to, if its cracked or any rust i would replace.

I have a 1989 5-series BMW which sometimes stalls after changing from reverse to drive. It also sometimes shakes when first driving in reverse before changing to drive.

check and or clean the (IAC) idle air control, this is what controls idling on most of todays cars and light trucks. if iac is removed for cleaning. clean out where it mounts to engine or fuel injection unit. good-day !

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
