Bout to give up NEED HELP!!!

[thompson13]

Ok well I'm on about week two of trying to get my sr20 running correctly. It idles like a dream until I go to rev it. If I quickly jab the throttle it'll fall flat on it's face but if I ease into it, it will rev but it bogs down. Its not the maf (goes past 2500) already fixed that problem. I put a brand new harness on. Had an isis intake manifold on it, thought that was the problem so I switched back to the stock one and still does it. Already tried, ignitor, injectors, pressure regulator, maf, coilpacks, plugs, and ecu, checked codes and it is throwing 34 which is knock sensor. Would that have anything to do with my problem? We timed the cas last week to right where it should be. Its 11 o'clock here and I believe the neighbors are starting to get with my straight pipe so its time to call it. Plan on checking the tps tmro. Any help would be appreciated...

Check for boost leaks.

And no, not visually. Pressure test the piping. Here's a thread I found by searching - zerothread?id=422385

is there any sign of the car running increasingly rich? ive also heard people replacing things like alternators/batteries at this point as a last ditch effort and found that their current setup was producing so little spark (stuttering and bogging not so much stalling out like your setup) that they couldnt rev past 3,000 rpms

I had the same problem and it was a boost leak. I figured my pipes were tight enough or they would start to bend and they weren't. Also had a timing issue, but main thing was that leak.Start with that...

Check your TPS as well and verify that it's, and don't quote me on this but .37V closed throttle. 4V open.

Double check those numbers.
