i have a 98 jdm gsr motor with 9:1 je pistons. it has a full race stage 3 kit with a walboro 255 and a vortech 12:1 fmu all in a 97 dx hatch. when the car starts it has a rough idle, and it wont rev past 3k. it runs like *** and throws about 5 CELs. ive tried 2 different distibutors, and everything else i can think of. i have also tried various ecu set-ups. OBD1 p28 w/ conversion harness, OBD2 P73, OBD1 p30 w/ conversion harness, all of which have slightly different idles and all run just slightly different. sometimes it will backfire and its running pig rich. if anyone has any suggestions it would be greatly appreciated. thanks
