I recently bought a 99 dc2 with a jdm b20. it has a gsr obd2 harness converted to obd1 with an LS ecu..now my problem is its giving me code ((#3-#41#54)) so that is map sensor,oxygen sensor,and crank fluctiouation sensor. now is this because this is a jdm b20 and it has no crank sensor..i think it is . but what about the map sensor is that whats causeing the bad idle. i thought it was my tps sensor,but it never gave me that code...please help me out

 

SOUNDs to me like you need to find a 99 LS wiring harness and ECU, then go from there, most wiring harness conversions end up in CEL if they are not done properly, in this case without anymore information that is all i could tell you.

 

WELL I CANT DO THAT BECAUSE IM GOING TO SWAP THE HEAD IN A COUPLE OF WEEKS TO A VTEC HEAD SO I NEED THAT HARNESS..
