yea it would be good it u could say or paste scanned pages for:
*IMA sensor resistance and/or voltage -not sure if its in manual
*CO in exhaust without cat. and with propper IMA adjusted
*Throttle angel sensors resistance and/or voltage with closed throttle and fully opened

this all should be in fuel section of manual(was in accord manual). thanks
once again, engine is B20A1

tried looking threw the haynes book but quite useless. throttle angle is mentinoed only once in a diagram and is not explained any further. could you give me a bit more info on 1 and 2 like what is the IMA sensor and ill have another look

IMA sensor is that one potenciometer in black box with whom we regulate fuel mixture and regulate/measure CO in exhaust.
throttle angel sensor is a potenciometer wich is directly connected to throttle coil, it changes resistance according to throttle coil angle change. its position needs to be propperly adjusted the way it responds properly on throttle change. fuel mixture is based on this one as well. pure english, i know. hope you uderstood me
B20A is closest engine to B20A1, so info on B20A is much more worth for me than A-series.

Where are you guys getting these manuals? Everytime I look for a wiring diagram I run into a brick wall!
For the Prelude specifically or just for cars in general? Google is a good start. Vehicle specific web forums are also good as well but you usually have to register to search them.
