not sure if anyone here will know, i posted on pgmfi also, but figured i'd try you guys as well. i'm repairing/repaired this obd1 pr3, but can't figure out where one of the traces goes without removing ic9, which i'd rather not do if i don't have to. i goes from pin 5 of rm3 to pin 18 of ic4, then appears to continue from pin 18 of ic4 to maybe pin 18 of of ic9, but i'm not positive, any help would be much appreciated. on another note, before any repairs (as is in pic), the car ran fine off of the stock rom, but the cel would not function at all, now i havel all of the traces repaired except for the ic9 to ic4 trace, and the car runs fine and cel functions properly with external rom also, the only thing i've noticed is a low cold idle, but that could be from something else in the .bin as well. tia.
