When im driving slow in low rpm my car keeps stalling meaning when i let go the accelerator and the rpm slowly drops it just keep stalling you can feel the car pulling back and forth strange agin the tip box changes to gear 4 at speed of 45km. And once it drops to 40km it changes to gear 3.

Is there anything wrong. The stalling problem also occurs when i accelerates and let off my foot from the accelerator to let the speed of the car go downs and the car just stalls before it stops

hmmm it could be the stepper motor. cos usually when your car stalls while almost at 0km/hr , its usually the stepper motor. Even at traffic lights when your car is reving at low levels and when u let go of the clutch(in the manual), the car stalls!

Does sound like the good old stepper motor. There is a way to clean it for a temp fix - didn't work on mine, so I just stuck a new one in, but could be worth a try. My first symtoms was the car reving up and down while i was stopped at the lights... everyone thought I wanted to race them!

Plenty of posts on here that can explain it better than me.

where is it located? wheres the stepper motor located.

i have that problem too. few months ago when i went shopping i start up my car the rpm just go all the way to redline. everyone thought i was crazy.

when my car was towed into the workshop the guy told me is the sensor near the the throttle body where by the butterfly open and close when u step the accelerator. it cost me $450 to fix that. thats a rip off for a sensor. the sensor is at the point where the 90 deg bend is connect to the throttle body where the engine suck in air from.

The stepper motor is immediately underneath the air pipe that goes into the throttle body. It's got 2 bolts, and an electrical plug. Looks like:

bingo thats the one guys i pay off $450 for that thing plus installation
how come my car is the same as before beating around the bush im actually referring to that.

oh yes i change that one haiz
what am i going to do with it the car really sucks when it stalls so im pretty sure its not the stepper motor i change it
thanks for showing the pic.

woah... $450 just for a stepper motor Seems ozzy prices have a huge mark up. It's very often MUCH cheaper to sourse the part yourself, or have a search on here before letting a mechanic have free reign with your chequebook.

I'd suggest testing your ECU for fault codes. That might narrow it down a bit.

yeah $450 is way to high for a stepper motor! i paid $150 and my mechanic ordered it from eastern states and arrived within 2 days!

thanks a lot guys cheers
