fuel?boost leak?no clue?

[JohNneGST]

just recently my car started to bog out in high boost (15psi) , and it has started to bog at low boost(10psi) , so i repalce the fuel filter and the problem went away but now i have another, when i give it more then 50% throttle the hole car starts to rumble at like 4k , and it rumbles bad , so i let off , but if i hiold it past the rumble to about 5.5k the whole car kicks in at once and my BOV opens and the car goes no wheres, and its getting worse , and help please.

I have almost the same exact problem in my 1g. I can't get the car to go over 5000 under WOT. It feels like I hit a wall. Now If i go up to redline under 50% or so it will make it. I only see 10 psi and no more. Stock boost.

if it pulls and it feels like you hit a wall then more than likely your are hitting fuel cut. Do a search and you can find some solutions to this problem.

What do you mean by rumble??? What do you mean by BOV opens?? More details would be nice and it would also help others give better answers.

I have had two instances(sp?) where my car would bog/fall on its face at wot when boost would kick in.

1. I would go WOT and at about 3,500rpms it would stutter and slowdown. After that it would pull hard again. That was when I first got my car. All I did was change the plugs and wires along with the oil and filter and it worked again!

2. 4,500 miles later (like 3 days ago) im driving and decide to WOT. Pulled like a mofo thanks to 16psi and as soon as the needle jumped past 10psi the car would misfire alot and buck. Changed plugs along with oil and filter and she is happily boosting 16psi again.

ok, not even at wot , but partial , say 50% throttle when i hit around 4k , the car doesnt quite hit a wall, it slow down alot , barely wants to pass 4.5k but it does and at that time the car begins to stutter,vibrate , rumble, then as it passes that point the rumble goes away and and suddenly everything decides to work but as that happens the BOV makes a loud popping , i think its being forced open and the car doesnt move at all, but why would i have hit fuel cut , its at stock boost , just changed the plugs and wire , getting coils soon and i cleaned the cam sensor entirly , its really weird , i never felt anything like it before
