1990 Mazda 626 Car starts, idles and runs very well when cold however whwn its hot the car is hard to start and stalls. So far the idlde air cotrol valve and mass air sensor have been replaced . Each...


Honestly sounds like the throttle position sensor, if the car is cold it will be choked and thus the throttle body flap almost closed easy to crank, more fuel less air.... when the air warms it moves the throttles actual flap opening wider, thus more air less fuel and harder starting, not as much fuel to combust and if the computer cannot sense the correct position, it will cause acceleration hesitating, poor idle, and what is called stumbling, where you press the gas and it kind of sounds like the motor sputters for a second and then goes or the occasional surging if at highway speed of say 60 mph and you feel the car kinda speed up mile or 2 and then back to the original speed.

My 93 nissan p/u had that issue, but the tps was replaced and it takes 2-3 revolutions on the motor and it's running smooth, hot or cold.

Hope this helps.

You would need to figure out if the problem is too much air or not enough fuel.
The carb has three internal circuits - - idle, cruise, and accelerate.
Fuel flows thru each circuit from the bowl to the venturi.
You could have a vac leak that is allowing too much air to enter the intake, or the idle circuit on the carb may not be adjusted correctly after the engine warms up.
Or it could be something else.

98 Corolla stalls or stumbles when cold


It sounds like you may have picked up some small debris from the bottom of the gas tank when you ran it empty. You may need to run a fuel/injector cleaning solution through the next tank of gas to clear the debris and consider changing your fuel filter too. Sea Foam is a great fuel additive and I recomment trying it full strength. Hope this helps!

Car stumbles, backfires until warm


You need to replace your distributor. There has been many problems with these. I had the same problem with my 1993 villager and had tried many different things and none worked. I went to a junk yard and got a used distributor and now it runs fine. I would try this before anything alse.

Runs poorly while warming up


auto choke controled by the hot water system,sounds like someone has disconnected the pipes somewhere along the line as they were leaking,on or around the carb should be a round thing with two water pipes and inside is a bi-metal strip,which is most likely working but with no water through it or through the inlet manifold to preheat the petrol vapour hence your problem.soloution buy a small engined europen type vehiclelike a kangoo or berlingo and recycle the gas guzzler you have now.
