Hopefully someone out there has had this happen to them and figured it out. My gn is giving me problems, it almost seems like a short. Under WOT for a few second the car will basically shut down(not just a miss) the check engine light will flash on, the engine will shut down and the radio will even turn off and then come back on as if i turned the key off and then on again. The engine will catch itself at idle but then i cant give it more than about 1/3 throttle without it stalling? And now today it did the same thing just cruising about 55-60? PLEASE HELP ME!!
ps. i just put a new alternator on about a week ago.

Did this happen before you changed out the alternator?

Did you check for a code?

Check the main wire to the battery from the alternator and also the positive battery cable where it goes under the passenger side header.

it did do this just before i changed the alternator. I was planning on going to autozone to have some codes checked this afternoon(i dont have a scantool yet, ive only had the car for a month or two).

Don't need AutoZone. Keep them away from the car. :nono: Just a paper clip.

I checked for codes and it pulled up a 42 code, and the site says there may be a grounded or open wire, where do i look?, thanks keller
