Bogging Problem During Inital Driving

[spoold]

Ok guys, i actually have a problem, and im quite stumped.

I recently did a boost leak test and DID have many leaks. I fixed every, and i mean every singly leak and replaced all my gaskets on BOV/TB/BISS/IM and every other leak.

Heres my problem:

This happens when water temp is still warm, and only seems to happen after ive driven, then parked, then get back in (say, go to eat, park it. come back out, car is still warm, and then this happens)

I go to accelerate and if i try to accelerate past like 1/8 throttle, the car bogs, shutters, and shakes. Boost gauge reads that its not making boost, yet if i let off after bogging it the BOV definetly lets loose. If i rev it in neutral, or simply drive realllllly slowly for a while, and try to boost, it goes away and never comes back until i park/return.

It only does it randomly, but when it does it, the whole car shutters and it wont accelerate.

Boost leak test: done and solved. I am unsure as to what else this bogging could be cause by, especially since it is random and only when i first start driving?

Any help, or any more information needed, please feel free to ask.. thank you!

MAF sensor? Fouled plugs? Exhaust leak (cracked manifold)?

Things I could think of off the top of my head at least. But it is strange that it's intermittent. Any CEL when this happens? It could be an ECU problem too.

ok let me 1st note:

I have been venting on my stock 2g mas for about a week and a half due to the fact that i just put my new FMIC on and my stock recirc kit will not reach to my greddy type s. I have nevere had this problem, it just started today. ive been too busy to go get some radiator hose to make a longer recirc tube

and i do have a leak on the exhaust manfiold gasket near the PS bracket

Plugs, however, were JUST changed with NGKK BPR7ES's gapped to .028 (im at 17 psi)

I also have a CEL due to not having a second o2 sensor (on the catback part of the exhaust) but i have not had an o2 sensor since august of last year

My rear o2 harness was cut, also throwing a CEL for me.

Haha, remember in your post on the boost leak test...I commented on you venting (which you weren't at the time)

I doubt that venting would cause this, but it is always a possibility. Possible injector issue?

Is your MAF hacked at all? I know you want to avoid that on 2gs. But I don't think that I really would have any solution to this (that I have experienced) and I don't want to give you false information.

On a free and easy note, try the ECU 'reset' trick. Unplug the battery for 5 minutes or so and then try it again, that will clear the codes and who knows, MAYBE fix it. I always try that if I can't figure out a problem.

yeah ive never been venting until my Boost leak test (which was my FMIC install at the same time!)

after putting everything back together the friggin recirc tube owuldnt reach ><

My car ran like ass when I tried venting my BOV. Sounds like the same problems I was having. Even at normal driving it was bogging & cutting out. I bought a new 3" intake and put the recir tube back on and it solved my problem. Hope that's what it is for you.
