I have a 04/04 350. Last month I installed SAFC 2. After 2 weeks, while I was driving in first gear the car just shut down like something went dead. After that I couldn't start my car but my battery is fine cause the stereo and everything else is working except the SAFC. I towed my car to where I installed the SAFC and they said it might be ECU.........what happened? Does anyone know?

 

Check Oxygen Sensor plug in front of firewall in engine bay. Just maybe?

 

thanks for the reply bro!

 

Why did you just install an SAFC into the car?

What mods do you have that would need such an item?

 

header, high flow cats, exhaust, CAI, I was running lean on the dyno..........

 

Where did they get the 12V from to power the SAFC? If they tapped into the power wire running to the ECU, that may be the problem.

 

N.P. Just make sure to tell us all what you find out? Good Luck, Dave

 

What do you mean?
