Engine code help
Calling all Technicians, Lol!
I did cat delete, & headers, and I know I need to get it tuned.
Here's the codes I'm getting:
P0443 Purge Solenoid Valve Control Circuit
P3441 & P3449 Cylinder (1,7,6,etc...about 4-5 cylinders) Deactivation Solenoid Valve Control Circuit
P0135 H02S Heater Performance Sensor 1
P0060 H02S Heater Resistance Bank sensor2
TIA I really appreciate this community and being able to come to you guys

ALSO, the tranny seems to be shifting harder since doing all this. Would that have anything to do with the tranny breather Valve/hose (came loose during install), or u think a tune would help? Thanks Again!!
