Im running a obd-1 ecu on my 99 gsr in my 92 vx. There is a black sensor on the very top of the intake, and it has 2 hose comign out of it. do I need that sensor casue im using obd-1??? The main reason is becasue I don't have any place to put the hoses. hahaha

 

i think you're talking about the evap purge sol. those hoses go to purge can

 

how come the hoses on the purge can are smaller than the hose on the sensor on top of the intake.
