but happened once and only at that speed, also I know that 4th cyl coil is not in best shape, I ll try to change this also.

engine was running like hell, had a BT clear codes and everything came back to normal.


thank you all for your support !!

[e93ro]

getting again those cruising relaxed on highway - knock sensor 2 + 3100 boost deactivation.

at the track -pulls great !!!!

wtf ?

It might be from our restrictive emission system (happened first after c-less DPs install) or should I worry about my pistons ?

You left your mods on the car/and JB? Is this thing under warranty?

[e93ro]

mods on, warranty not anymore. on hway does that even on map0, so like no tune there

hmmm 175???? really?

coils are cheap. maybe that will help with the misfires. Have you cleaned valves lately?? (sea foam)

Knock codes are usually bad, running to high of a tune or bad sensor (never heard of that before).

boost deactivation happens occasionally when you have a reoccuring misfire in the same cylinder. I had this problem when my injectors were installed improperly. Misfire means plug/coil/injector issue. Once when I was taking out one of my plugs, I pushed the gap together just a hair and caused a misfire situation. Fixed the gap and all was well.

Injectors were recently redesighned, maybe its time for some new ones?

I have 2 extra new style injectors but they require software and 4 other new injectors to work properly. I'll let mine go for $120 each ($170 at the dealership) and they have less that 2K miles on them.

Good luck!

175 is easy to get to, anyway wasnt too much higher than that until now.

My problem is that i am getting those knock codes even on map0 !!!! that means almost stock, and NEVER got that on a drag race for example just when cruising almost constant/ relaxed on the highway ( +/- 100 mph ) Already changed 2 defective injectors but problem is not gone.

I will try removing dpfix as well and see... as codes came after DPs+dpfix install

[Kcyrusm]

Was this issue resolve? If so, how?? Please reply!!

I am having same exact issue with signal 1 instead of signal 2 though.
Codes: P2e68 and 3100

Mine started happening after AR Design Catless Downpipe install as well. Code pulls and goes into LIMP mode when light cruising at around 2100 rpms.

It happens with Cobb tune installed and when Cobb is uninstalled. WTF??

Make sure the O2 sensors aren't swapped, that causes all sorts of screwed up running characteristics, since you say the DPs were just done... Was there a DP fix installed, too?

[Simon930]

I'm having the same exact codes
2e69 and 3100 only at cruising

Car pulls crazy at WOT but i am getting code 2A87 after 2 or 3 WOT's ?

[._.]

I got 2E68 (bank 1) and 3100 today, they showed up with the awesome 2AAF and 29F3 codes. Oh, Joy!

If the O2 sensors are backwards, would this throw codes or just have the car act differently?
