sr20 will not rev past 3k

[kbui]

hello,

To start, i have an sr20det with a z32 maf. at first i thought it was the maf; so i checked the wiring with meter....turns out the wiring is correct. I replaced the maf with a know working one....still won't rev past 3k. i cleaned both sensors and still nothing.

Its running real rich at idle and like i said won;t rev past the 3k in neutral. anyone have any ideas? i checked for a boost leak, but found nothing. however my boost gauge does say -12 inHG. If i remember correctly, my past sr20dets have read in the -20s. Maybe I have the vacuum hoses hooked up wrong?

as it sits it idles alright and does smoke, but i figured it is because of how rich it is. can it be tps? but a tps wouldn't cause it to run rich. I replaced the iacv, thinking it was that, but still nothing.

What do you guys think?

thanks
