Same here.

There is one person who avoided dtc p1239 in Korea. He's been in ride car for five years, and he didn't use the extended harness provided by stillen in the first place.
I twisted the wire of the OEM cable from the starting point to the throttle body. I'll try that and write down the results.

I've had no problems since I switched to the michigan motorsports cable and wrapped it in teva tape and an insulating sleeve. It's been almost a year.

Would you have their part numbers ? :tiphat:

I'm curious how frequently this occurs, so far been supercharged for a year with no issues. Should I have an extra laying around?

No not necessarily (Stillen ext cable) because it won't necessarily fix it. You just never know if and WHEN it will bite you. So unpredictable.
I'm interested in the Michigan Motorsports one as an alternative though.

Sure, here you go...

Thank you! :tiphat:
That's just the MAF extension. Did you get a TB extension from them to?

Thank you bro: icon18 :

I hope for your advice.
How many miles did it run?: 해피 댄스 :

Nope, that's what I'm using as my TB extension.

I have about 3,200 miles on it so far

Thank you! I just bought an extension harness from Michigan -motorsport

lol

OK thanks for that.

After using the Michigan Motors TB harness, hellish p1239 no longer appears. I drove 1000 miles hard.
I've been on the track for 10 times.
There is no problem with harsh track driving.
