Default What the funk is going on? W/video!

FYI: 07 sti "stage 2+", e-tuned with Cobb AP and has viper remote start.

As I was driving the other day my sti suddenly started losing power so I pull over to the side of the road just in time for it to die. Try to restart a few times, would start and stutter for a few seconds before dying. Check code with AP and got P1572 for the immobilizer. Try pulling battery terminal off to reset, didn't help. Leave it on the side of the rd.

Go back next day, reflash tune with AP a few times, finally get it to stay running but rich, limp it the mile back home to my driveway. Seems good enough so i drive it short commute to work and the process kinda repeated...loss of power, stall, reflash, drive halfway home stall again etc.

See video, any ideas??

Check your wiring. Ive done a few car installs, where I rushed it, was sloppy and over time wires started touching each other or simply received loose connections.

I would start there.

Sounds like you have to hunt for the Immobilizer signal wires. I don't have an 07 manual but in the 08 STI manual it says to look for plug in "B136" on the ECM for pin #26 is signal 1, pin #34 is signal #2. It doesn't say what they feed off of and I don't see any repair procedure to follow, you might be chasing a bad ground for hours or days.

Good luck.

Thanks guys. I did take a gander under the dash for loose wires and didn't see anything obvious. I'll have to dig a little deeper for that immobilizer wire!

Damn electrical problems

Unplug the viper. It should have a Molex connector or something similar.
