Also new base map for 4bar and help please let me know dizz is what iv been told idk tho

 

Basemap? if so that is your problem

a basemap is meant to start a car to check for proper operation and to allow for tuning to be done, under no reason is it meant to be driven on...

 

ya basemap from phearable.net set up for the car just until i can get to the tuner but would a basemap cause that problem and randomly flashing check engine my air to fuel is perfect so is timing

 

Nothing on that basemap is perfect.... that's why it's called a basemap.

they sure as hell aren't meant to be used to beat on the motor. don't drive it until you can have it properly tuned

 

Do you have any good tuners you recommend ?
