Like most owners of 98 Prelude's, my Check Engine light and ATTS light came on recently and have been staying on. I have had it read by an autoshop and it said EGR valve was bad. I fixed that problem and guess what? It came back on!! I have checked my fluids, ran the code, reset the code to see if it was just a wiring thing (it wasn't) and now I am running out of ideas! I need to know if anyone has ever resolved this issue. It's very frusterating. I have done some minor mods but none of which would make my check engine light come on. Please, any help would be greatly appreciated. Thanks
