So what have we done so far 

 

Checked for Pipes lose split cracked ? 

MAFS        Done

02 sensor  Done

Idle control valve ?

Plugs changed ?

Coil packs looked at ?

 

Just trying to get an idea so don't go over old things twice :) 

Idle control valve it's EGR? Because on my previous forester idle control valve was on throttle body but now on throttle body i have MAP sensor. I check on opposedforces.com.

I'm not 100% with the 07 fozzies 

have you tried to clean the throttle body and plate, they can get pretty gunked up ?

I cleaned.

:(

Spark plugs changed but still a feel slightly shakes. Today i have unplug Maf sensor and start engine CEL light but shakes exactly the same. When clear ECU and plug MAFS CEL gone. Is it possible that ECU doesn't show any issues on MAFS but maybe it is broken.

When i check live data MAFS show 2.9 g/s but i don't know that is correct or not.

It is possible it happened to mine. I had replaced the MAFS with one from a scrap yard but still same thing happened so I changed a bunch of other stuff idle control valve plugs coil packs. Ended up changing the MAFS again and like !Removed! magic it was running fine. But I know it's not cheap to replace :( 

90% it was maf sensor. I still testing. Thank for all.

Great to hear - keep us posted, but hopefully you have it sorted!!

Issue sorted this was MAFS. Thanks.

Woop-Woop glad to hear it's sorted mate :D

Bit of a pain the MAF :)

Brilliant to hear!! does seem to be a failure that throws up a lot of issues the old MAF sensor
