I removed distributor cap and checked. Re-ired the spark wires.
Adjusted AFR today from 9 to 13,5 at idle.
Engine is running fine at idle and boost. Will log AFR now.
One strange thing I noticed today was that when accelerating in a turn, left or right, it seems like engine is loosing ignition or fuel, and stuttering and ends with a bang in the exhaust.
When accelerating straightforward all is well

That's weird. Got an almost empty gas tank...gas sloshing away from the intake and sucking air? (long shot, I know, but stranger things have happened).

Or, a bad electrical connection either fuel or ignition related...some wire somewhere moving in response to sideways engine/body torque. Try tugging on every wire you can get your hands on with the car idling in the driveway.

Check both fuel pump relays that they are fully seated in their sockets. you may have a loose connection where one is cutting out intermittently.

You may also want to check that the ground strap from the engine to the rear body is tight and clean, too.

Trying to figure out things that could be affected by the engine moving in its mounts from left to right...

could also be a wire or plug/coil lead getting bent or compressed or shorted during right or left motion...
