Comments on: Does your engine idle or stall?

I have a 2009 wrx with 17K miles on it. All of a sudden at idle it sounds and feels like it is missing. I read about changing the plugs but not sure if it is the right solution. I am hesitant to take it to the dealer b/c of aftermarket DP and Cobb AP. I have messed around with the idle rpm and timing but nothing is helping. I have had the Cobb and DP on for 10K+ miles with no problems. Anyone else experiencing this?

My 2010 WRX does the same thing during cold starts.

On a different note, when shifting into reverse, the WRX appears to have a load gear engagement if that is the best way to word it. It is just a lot loader engagement then shifting into first for example. Is this normal?

Sorry, Just found this blog and seem to be commenting on every post!

The rough idle is normal, the rev hang (revs to 3k pulling in the driveway) is normal, if annoying.

I haven’t heard of a new version for the ECU software for the 2009MY. So a reflash will write the same program into ECU with the same behaviour.

Sounds like ECU needs to be remapped or there is a problem in with the throttle body…check them first.

Shift to neutral and release the clutch. The high revs will go away. For some reason ECU is keeping sometimes the revs up when you want to shift into the second gear. Some say it is a bug, others say it is a protection against stalling. But at least it is predictable.

My engine revs up to 3k rpms when I pull into the driveway on occasion as well.
No stalling issues, however.

Thank you, Geoff!

This is a normal boxer engine characteristic. Nothing to worry about.

I haven’t had this issue, but it could be that I haven’t been paying attention. I will keep my eyes open.

It is common for a car of this set up to be a tad finicky when moving slowly. The turbo is really not doing much at low engine speed therefore putting all the force of moving and a AWD drive train on a small 2.5 L 4 cyl. My guess is a smooth foot, and try not to overload the engine with out the right amount of throttle.

I will talk to my service manager friend when I am in next.
