90turboMX5

I've been trying to fix this problem:
-The RPMS wont stay steady at idle (they jump from 1000-1200)
- Injector pulse width jumps as well
-AFR jumps from 12-16 at idle and 13-17 under load
- The RPMS wont stay put under steady acceleration
- Car stumbles when driving it.


I've messed with VE table and MLV, cant fix it. Also changed the accel enrich, but nothing...
Here is a log done without driving, at my garage.
And my MS files.

Any help will be appreciated.

Thanks
