I have swapped a b16 from an 93 xsi teg into my 91 civic EX It runs, but there are problems. problems: 1. will run on cold start, but after you shut it off and try to start it again it will idle improperly and when you try to drive it it has no power, it bogs out. -changed the main relay, thinking it might be the ignitor 2. is the car suppose to be fairly loud, i have no aftermarket exaust, and it is loud. - i know i should change the exaust, but it alread has good flow through from rust. 3. electrical flickers after high rev and when riding down hill in gear w/o pressing gas. -changed the battery 4. Engine light stays on - don't know how to read the engine codes on the ecu. it is pr3 obd-1 All my problems could be the wiring but i think i did it right. obd0 to obd1 i you peeps can help thanks. sorry new to this forum.
