I feel that there is a bigger audience in this forum so someone might be able to help me out...

Everything is bolted in and cranking and the car is starting and runing...
but it sounds like the idle part of the engine is up the creek...

My First problem was my P13 (JDM Prelude) ECU is stuffed.. When i connected it the CEL was always on... the engine would start but didnt let me rev past 3000RPM... I tried to get the codes of what could be wrong but it didnt blink at all...

Checking my wiring it all apears to be fine... vacuum hoses apear to be fine as well

Now i pluged the POC (F22B NON-VTEC ECU) the car starts, the idle problem is still there... but it lets me rev past 3000RPM... i get check engine light and i get some codes...

i sorta cant interpret what the code is but this is how it goes...


........ON....ON.........ON....ON and repeats this ... could only be the 3 codes...

ive tried a known working map sensor... so i dont think its the MAP.....
HO2 sensor... ive got a spare one... but havent tried changing it.. but i dont think this could be why my idle is not wanting to keep the engine running... when it drops below 1000rpm the engine shakes and the intake sounds like its choking... give it more gas the engine sounds ok... otherwise the engine will stall

Just a question but i read the Chiltons manual on how to adjust the idle... but is so bloody confusing... you gotta take out the vacuum hose and reset the ecu and adjust the screw? i thought the Idle control unit does this?

can someone explain this to me...

also with the vacuum hose, the solenoid on top of the injectors i removed this and connected the hose straight...

thanks for any help...

is there a reason why my radiator fans do not spin when my engine is running but when i turn the car off it starts to go on?

Also i have given the car a test drive with the Accord ECU while i wait for my P13 ECU to be replaced... (could this be why?) The car has no torque wat so ever but i can hear the intake scream like if the car was working properly at high rpms

Ive been reading up on the the archive post, it sounds like it could be the IAC solenoid, well bascially my car just stalls and the car will not idle or will idle really bad at really close to stall revs....
