GT still having WOT woes...!

[wohorsy2002]

I posted this earlier but do not think I explained it well enough.

In my car most of the time it will run fine.. however every once in awhile, maybe 20% of the time in 2nd 3rd or 4th gear at WOT the car will shut completely off and the car will not start for 10 seconds or so. I believe it possible has something to do with ignition, maybe a bad ground for instance. I just wanted everyones input. The car was tuned at murillo motorsports about 1 1/2 years ago and was set very conservative for daily driving.

Dude i was having trouble kinda like that a while ago and it was just my o2 sensors. I don't know for sure man, but no one else posted so i figured i throw something out there. Good luck man hope ya figure it out i know what its like having your baby limping instead of galloping.

Ya no doubt.... and the weird thing is that it only happens every once in awhile. When it runs right its perfect but there are a few things i will check now and it will narrow it down.

Yea if it was a ground like you were thinking i'd see why id did it at wot. its mybe because when your motor shakes under acceleration maybe it's pulling on a ground and shorting out. I don't know thats a tough one. Let me know what you find.

I was just out in the car and did two WOT pulls

1st pull 2nd Gear- Fuel pressue went to nearly 50 and stopped but car did not die

30 minutes later....

2nd Pull 2nd gear- fuel pressue stopped at 40... spiked to 60 for a blink of an eye then car died....

fuel pumps?
