Default WOT problem cought on tape!

well it was an extreamly hot day today and a was driving the car for about 45 mins and the problem that i had at NEBF and on my GXPwheel road trip showed up again, but this time i had my camera ready and shot a vid, so now you guys can see what it is that is wrong without my lousy decriptions

as you will see in the vid i cant get the RPM above 2500 when im not babying it major



I know i have to check the fuel pressure but i dont have the tools for that and this problem isnt constent, it just shows up fron time to time so im ever prepared for when it happens

In my opinion, that is a fuel pressure problem. Mine did that exactly before I got a new pump. Why is the Check Engine light on in the DIC? Got any codes?

no, it only happens when it is warm but it doesnt have to be over normal temp to happen, however today it was running hot because i was in slow traffic

I'd say its a clogged cat. Nate (lakeville SSEi) had the same problem and it was a clogged cat.

Would a clogged cat cause boost to be lower? I thought it raised boost pressure.

i dont know the answer to your question, how ever i do know that the Cat is NOT my problem. that was the first though and i replaced it with a highflow and am still getting it.

also i forgot to mention right after i stoped the recording the engine made a loud KNOCK at which point i babyed the car the rest of the way home (only about 10 blocks)

Sounds to me like a fuel starvation problem to me. My mom'* buick had a problem like that and we replaced the FPR, no problem after that, but I cannot guarantee that it is the problem.
