I have a 2001 Mazda protege. Car was running fine until a few weeks ago. When I come to a complete stop at a traffic light the engine tries to stall. When I try to go it kinda feel like it jerks but once the car is going it feels normal until I come to a complete stop again.

First eliminate all vacuum or air leaks in the system. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

Hello again.

Did you test all 4 cylinders? I would remove one spark plug and test each cylinder to see if all 4 cylinders are receiving spark. Plus the removed spark plug in each different spark plug wire to test. When cranking over all cylinders should have spark. Let us know after testing and we'll go from there. Hope this helps and thanks for using 2CarPros.
