Hey guys, today I drove my ss it’s hot here and I drove quick just as an info. So I drove on the highway and after that I drove for cool down, as I did that the engine light popped on. The codes on the title and picture were shown.

what I changed: MAF, MAP, K&N air filter, Sparkplugs, Ignition coils and I cleaned the air box. That’s what I have in mind currently.

can you guys help me ? Is it the K&N?

 

What you changed and what you have in mind seem to be the same thing. I'm not sure what you've done.

 

Oil on the K&N? Too much would be the P0101.
Don't know about P0191, but since it is a circuit problem start with wires.

 

yes that’s what I have done to it

 

filter was new no additional oil has been added.

 

When I got P0101, a new air filter fixed it.

 

is the K&N the oiled type? They are famous for destroying MAF sensors.
Did you recheck the MAF connector?
Did you check the fuel rail pressure sensor connector?
The MAF and FRPS are in close proximity to each other, maybe some wires got frayed.

 

A good cleaning and very light mist of air filter oil on the dirt side of the element should correct it

 

Two sensors giving you trouble at once may be a sign of a failing battery. Hot weather kills batteries. Could be a problem with a ground.

 

yeah it’s been sitting for some weeks and wasn’t on the battery charger.
