hello everyone here is my problem i just bought a 99 civic si (i bought it with the problem) it wont hold and idle u have to turn it on WOT and boggs until it gets past 3k and then revs up perfect i drove it on the freeway and it drove perfect IT JUST WONT IDLE!!

List of what i have done so far and have not worked

-Checked the comp. 155 all across yea a lil low but i have had lower..
-changed map sensor 3 times (checked the voltage to it and at the ecu its all ok)
-changed the iacv
-changed the whole throttle body
-pulled off head (i thought it was a bent valve)...it wasnt but i found out it has cp mid comp pistons
-put head back on
-changed spark plugs and wires
-tried a different dizzy
-thought it cud be a clogged CAT so ran it open headers
-tried 4 different ecus 2 p2t's and even used a jumper harness and tried a chipped p28 and a stock p28

wierd things i have noticed:
-it will idle at 1800-2100 if the map sensor is disconnected
-when i disconnect the tps it DOESNT throw a code for it being disconnected
