Hi everyone,
I have a Mazda Protege 2002 with the 2.0 FS engine. the issue presents in the following way
- When the car is warming up, let's say 10 minutes after turning the engine on, it randomly drops RPMs for less than a second and then it stabilizes.
- It does this for a few more times and then runs fine after the car is fully warmed up
- I noticed that during that time when the car does this, accelerating from a full stop makes the engine stutter a little bit, but only when accelerating from a full stop. Also when the car is fully warmed up, it doesn't do this anymore.
- It only drops RPMs when idling, it never drops rpm when the car is moving.
- the RPM drops more frequently when under load, like when I have headlights on and A/C.
Any Protege experts or techinicians that can help guide me in the right direction to start troubleshooting?
