Hi i just bought a 92 civic si and it has a B20 in it from a 2001 crv, has P75 ecu I think it has a 94 integra eng. wiring harness. The prob. i am having is the person that did this swap left off the EVAP purge control solenoid and the wires was cut, and also the wires to the IAC valve was cut also, but was hooked up, I am not sure the wires are right cause the EVAP purge control solenoid has a yellow / black wire as dose the IACV. How can i find out if it is hooked up right?? I bought a used EVAP purge control solenoid so i am going to hook it up when i find out what wire goes where. The car is throwing a code 1 the eng. light only comes on ever once in awhile, but it has a miss in it when its idling and when you let off the gas it has a exploding popping sound in the exhaust . Any clue what it could be?? Thanks for any help

 

if it is missing then you prodly need a good tuneup, if u where to buy a helmes manule u could figure out how to do the rest sold at most parts stores

 

Yeah i did the tune up before I posted for help.. Someone took the cat off and it has about 2/25 pip under it.
