i have a 98 turbo charged teg with hondata s200 with p28 ecu and obd1 conversion harness. ill drive it for weeks and it will be fine , then out of nowhere it just wont rev past 4500 ,its kinda like a rev limiter sound, and will not boost, then i disconect the battery and hook it back up and its fine till it does it again. also , can i use a stock o2 sensor in this car?
