Ok.. iam totaly new to the hole.. tuner stuff, just got a 92 prelude a week ago. and it is having a idle problme.. 700rpm - 1700rpm I got a new ( ICV) off my friend and it read 8-12ooms so thats not the problem. and i bleed the cooling system, that didnt work.. there are no vacume leaks. I was thinking the code for Map sensor could be the problme? just want to make sure befor i spend alot of money..

and if any one can help me with the other 3 codes ( 9, 2, and 4 ) that would be great, thank you.

3 MAP - manifold absolute pressure sensor
9 CYP - cylinder sensor
2 O2B - Oxygen sensor #2
4 CKP - crank position sensor

ok now, i reset my ECU by pulling the ( clock / radio fuse ) and now iam geting ( code 9 and 2 )

i reset it and took it for a ride about 5 miles so that map sensor and crank sensor code would show up.
 
What's so hard to understand about this? Just follow the codes. You probably need a new O2 sensor...
 
ya but would a O2 sensor, make my car rev from 700-1700 then back down when ever i idle?
 
also with that number of codes, double check the wires. Could be someones hack job. Especially since you bought it that way.
