Limp Stillen Supercharger dtc p1239

Dbeckwith

Following. Just ran into the same code and limp mode after an ecutek tune, so I tried the foil for now and rerouted the wires. Will see if it resolves the issue.

I've been on a New TB Cable with no Foil Wrap since my last posting. Taken two 500 mile trips .... no issues.
My cable is routed along the existing wire-loom across the top/front of the motor --> away from direct engine block heat.

Be sure to do these:

Read my note on the Idle Air Volume about how long the engine light should blink before going steady ... to make sure it takes properly.
Good luck.

Fantastic, thanks for the info! I got a quote from Stillen, I'll go ahead and order that replacement TB Extension Cable.

Dbeckwith

Replaced the cable, and no further issues here. Thanks!

Add one more to the list of people experiencing this problem. I just placed my order with Stillen, and I'll try the temporary foil solution until it arrives. Thank you for following up with results on this post, it was very helpful

Guys, Stillen has done an upgrade on the MAF and Throttlebody extension cables. I was having the same problem and after talking to the tech at Stillen he sent me a new cable set and it cured the problem. YOU DO NOT NEED TO PUT FOIL OVER THE CABLE.

It seems that the wire gauge Stillen was using for the crimp connectors was too small causing an unreliable crimp and intermittent problems. I know, I fought this issue for months until I called Stillen. After the new cables were installed it has been 100% reliable.

Did you need both MAF and Throttle body extension cables?

TBatt, Do you know when they Upgraded Cables ?

I still have the problem, but NOT Frequently.
Did the 'steering wheel lock' Disable, & when I loose throttle now ....
hold the start button a couple seconds until it Kills,
tap it back to the ON position, push it again to Re-Start the motor....
If you have throttle after that ...
you're still Rolling --> so back in gear, & down the road you go.

TBat -> Chill man. haha Baby Likes Bling.

I agree with this though. The foil wrap was being desperate. If you Un-plug, & Re-plug the 4 'underhood' throttle-body cable Connectors ... Then I think you will be ahead of the Foil fix. I did the foil, & praised it, & still have it that way.
I also Still have the Limp-mode glitch.

My baby just started doing this crap too. What a terrible feeling going dead in the water in a Z!!! My Stillen was on the first engine (before I threw a rod through the block in March with 22K on her) and it never did this, so I'll try the resets tomorrow and maybe add some bling to see if it stops. Headed to AMP in two weeks to kick some Mustang butt and certainly don't need to go limp on the track. Thanks for posting the relearn links wymoteeZ.

There is a guy on the myg37 forum who bought new throttle bodies, and the new Stillen cable/harness and said he still has the problem :-/

Very depressing, to be honest. I have the cable on the way and was all excited thinking that would be the solution. Maybe he didn't plug it all the way in, right? Sigh.

Stillen cables suck I had same problem until I had my son make me new extension cables. No problems since

Optimiser

I had the same problem about a year ago and my shop diagnosed and fixed it. One of the pins had a bad connection. It's been fine since (touch wood).

osburnrs

I was getting 3 throttle codes so I did the resets posted in this thread and wrapped just the connections with this stuff and ran it hard for a couple of hours. I had this on before the engine swap and thought it was useless but apparently not. No CEL's and no limp mode. Touches wood and got a little bit of wood while doing a happy dance!

The Stillen tech said that the new cable design was done late 2016 so if you have a kit before then it could have the extension cable problem.

My code 1239 was VERY intermittent. I could drive for weeks with no issue and then it would start to fail. When I went over the connections it seemed to be "fixed" but the limp mode would eventually show back up.

The new cables are working great and so far not a problem!
