B16 bogging in low RPM
This is an odd one.
I have a 94 GSR with a swapped b16. AFAIK, the swap was done well, by a shop. It runs great, no problems other than this. Plenty of power, hits VTEC hard.
Here's the problem:
At about 1400-1500 RPM, so under part throttle when warm, when controlled by the IACV when cold, or even if at that RPM in 5th gear, I get a sort of stutter/bog. It's only at this small RPM range and there are no other problems.
I was wondering why, when I got the car, the IACV was unhooked. Turns out this may be why - while cold, the RPMs tend to hover right around the range where it bogs, which makes the whole car shake and the RPMS jump up and down from 1300-1500 pretty violently.
Note again that this is ONLY at this RPM range.
Any ideas?
I just replaced the o2 sensor AND cleaned the IACV.

Re: B16 bogging in low RPM
I have a code 14. I will check the FITV.
Also, I have the following problems in the engine bay that may be contributing to this:
This hose is cut to a very short length on the front of the IM.
This hose connected to the TB is not connected to anything and just has a screw plugging it.
This is connected to nothing, as you can see by the hose - I believe this is the EVAP canister.
Where do I connect these hoses?

Re: B16 bogging in low RPM
In the first picture on the intake manifold, your PCV hose is supposed to go there, but it is capped off. Find the hose and also replace your pcv valve while your finding that hose. Probably was capped off for a reason from some one being lazy.
The last picture it looks as if you don't have any of the hoses to the EVAP Canister hooked up, aside from the one coming out of the vehicles body.

Where would the hose on the TB and the hose from the canister go?

Re: B16 bogging in low RPM
Can you get me better pictures please? I believe the EVAP situation, they didnt know where to hook the lines to because the GSR throttle body is different I believe.
