Did you do the prewiring yourself? Might want to double check that and make sure all your wires are in the right spot.

JayKay335i · 03-25-2011, 01:40 AM

Cant you check codes with the jb4?

You might want to post this either in the engine mods section or over on n54tech.com. That way you will have a better shot of Terry seeing this thread. Or just email him. Good luck!

SteveMD · 03-25-2011, 08:50 AM

What other mods do you have?

What map are you running?

Plug and Play or Pin Out wiring?

Sounds like misfire code? Those are normally plug, injector, or coil.

I don't get why people make these threads without taking the 3 seconds to read the actual codes first.

The traction control off may not be part of the issue - ive been having a problem when going wot at ~3k it goes into limp - havent ran the code yet but it is similar to a previous problem ive had with vanos - just a couple of solenoids and about to put them in - hopefully clears up the issue

Turn off auto clear. I never have that on for that very reason.

Auto clear is off by default so he probably;y just means the light is turning off and doesn't understand the code is still stored. But if a real code ever comes up with autoclear on giving a CEL you just switch to map 0 on the fly which also disables autoclear. Or just read the code right there on the dash.

Yea turn off auto-clear it throws up all kinds of codes. Id reset the battery too that always helps me.

mia335i · 03-25-2011, 03:23 PM

When I have checked it no codes .... I'm going to video tape it today -_- . also when it goes into limp mode the tranny shakes an exhaust to

Jeff@TopGearSolutions · 03-25-2011, 04:04 PM

Lower map and see if problem goes away... or look into replacing Fuel pump, injectors, plugs, or coilpacks.

FLoRiDa335i · 03-25-2011, 05:00 PM

I just had the same issues. Took JB4 out, went to dealership, and it better now. Just needed the new HPFP and New Injectors which were both on recall.

TotalBlackout · 04-08-2011, 12:23 AM

I have dual cone intake and JB4, both installed this week. Monday I had the HPFP replaced and 5 injectors.

Tonight at WOT in 6th gear at about 145mph, the car gave me a malfunction (1/2motor) message and I had no power. Map was set to five. Oil temp was one notch below 250.

I stopped car and turned it back on and everything appeared normal.

They replaced 5 injectors out of 6?? Wow.. You would think at that point they would just replace them all.
