Hi everyone,

So my mazda 2 DY has been having a rough time while in idle.
When I start the car, it cranks but stalls instantly or after 1-2 seconds. before it stalls wobble around 300-700 RPM.
I can press the gas paddle without problems, no weird noise or anything. But when I release the pedal it drops dead or starts wobbling around the 500rpm, where it sometimes climbs back to idle rpm or stalls.
When I keep the pedal pressed until it has warmed up a bit it does not stall right away. it again wobbles around the 500rpm and corrects itself most of the time.
When I come to a stop while driving it almost always dies, either warm or cold.

There was a crack in one of the hose's, which has been replaced but did not solve the problem. I have also cleaned the throttle body which did not help the problem either.

Anybody have any suggestions?

 

Remove the connector for the MAF (Mass Air Flow) sensor and clean the contacts of the plug and socket with contact cleaner or rubbing alcohol and reinstall it. If that doesn't fix it, have the MAF itself cleaned.
