i just bought a power fc and im having trouble getting the car to run right. the car use to have a modified harness to run a haltech e6k and the pfc plugs right in and the car starts but it wont idle by itself and when i step on the gas its really laggy and i cant hold a steady idle. i need to get this fixed please help me

and to mention when i turn the car off the commander stays on. im not sure why it is doing this

 

Yo need to insure that the engine has all the correct sensors wired to the harness for the PFC. Time to take the car to Jason!

 

yep its going today, lol it seems the car is on the road for one week then off for 2 o well thats a rx7 for ya
