11 codes P0171,P0172,P0174,P0175,P2195,P2197,P0300,P0304,P0 307.Other ones i set by unplugging things.Trims going from -25 to 46 O2's show working ok. Running perfect for a couple of hours today then shaking again all scan #'s good still set code P2195 again with no leaks found plugs 15 k miles ago no phaser issues im at a loss any ideas are welcomed

 

How many miles on the engine?

 

Re manufactured motor with 60 K Miles Plugs & cops 10 K Miles ago MAF Cleaned Throttle body cleaned seems to go wild when it gets to 10 below freezing.

 

New MAF sensor minimal improvement
New plugs minimal improvement
Found small vac leak repaired minimal improvement
looks like intake gaskets or plastic intake

 

Coils?

 

Clear all of the codes and see which ones come back.

 

Coils replaced po171 & po174 come back but only on cold days
At todays temp no codes at all runs ok but a little rough
