i have a 90 crx with a b18a1. when i rapidly floor it under 3500 rpm it bogs out then comes back to life. the only code im throwing is a atmospheric preasure sensor. would that be the issue? and also the car idles around 1700rpm and its very anoying wat would cause that? any input would be great thanks.

timing, spark plug or spark plug wires. let me know if that helps if not i can try thinkin of something else.

fix the trouble code and then see what happens

i have done all that a few times. i didnt do the swap. i bought it like that for 800 bucks. i fixed a few things here and there but just cant figure the bog out. my buddy had a crx si with a zc in it and it did the same thing. it really sucks. and the code i am throwing is from a sensor in the ecu itself(so read on a few forums) im gonna switch the ecu out when my buddy gets back to town whenever that is. but if anyonelse has input it is greatly apreciated. thanks

I have never heard of the Atmospheric Pressure Sensor. It might be the MAP sensor (manifold absolute pressure sensor)

I would check these three first:
MAP sensor, throttle position sensor, the O2 sensor. Check those first, make sure that you are getting a constant voltage to those sensors from the ECU.
