sr20 wont rev smoothly

[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, or act like a 2 step (kinda), 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 http://images.nicoclub.com/forums/images/smilies/angryfire.gif with my straight pipe so its time to call it. Plan on checking the tps tmro. Any help would be appreciated... http://www.nicoclub.com/Noah/dblthumb2.gif

Check your TPS voltage.

Open .400

Close 4.1-4.5 volts

if it's bad I have one for sale for 40 bucks + shipping that is good condition.

(I actually have two of them)

I would also check your plug gap, If your plugs are TOO close this can cause wacky off load conditions, make sure it's not tighter than .028

Check your BOV, ie open atmosphere. Some of the crappier ones actually LEAK Vacuum at idle, Make sure you dont have any vacuum leaks. This sounds like air is getting inot the engine past the MAF.

You are yet another example of a car that would benefit from my Diagnostic session on the dyno to get the car running tip top shape.

Thanks for the help... Think my problem was too big of gap on the spark plugs. Gonna try driving it again tomorrow.
