So, I checked the search forum and couldn't find a post that was similar to my problem..

2005 Mazda Shinka 6 Speed 45k miles.

Problem: Car at start idles fine without issue - after I drive for a bit and hit a stop light the car begins to dip in RPM's and I have to hit the throttle to keep it from stalling.

Possible Issues: Sparks / MAF / Coils /

I had checked the coils and they had no visible burn or wear. Didn't check the plugs.

Noticed today that after less than a mile of driving I parked the car and the idle was jumping around a lot - 1.5k-800 up and down.

I notice that the RPM's hit the 1500 mark when it dips below 800.. Possibly a fuel mix issue?

Suggestions are appreciated.

 

Definitely check your plugs. I remember I was hearing weird noises at high rpms in addition to your problems and found it to be the spark plugs needed replacing. If that didn't solve it, I would get a compression test.

 

clean your maf and eccentric shaft sensors. The reset the NVRAM (20 brake pedal press)

 

Could be a vacuum leak. Have you checked your lines?

 

Correct me if I'm wrong, any way to check for a leak other than to smoke? Also.. Cleaning the MAF just brush it dry?

I'm pretty sure it has to do with my intake somewhere. Not the plugs, because my spark is fine.
