The car is a 94 GSR with jdm type r motor, obd1-obd2 jumper, jdm type r ecu. I have this exact problem https://honda-tech.com/zerothread?id=1089291, I have replaced iacv, tried a gsr p72 and a chipped p28 all have the same results. I need some suggestions on what may be the cause. Oh, also i'm using the obd 1 gsr dist. and vtec solenoid, someone told me you can't use the gsr dist. on the r motor, but that makes no sence to me, is this true?
