can i just get the adapter and change it to an OBD1 ecu?

Yeah just order the harness and get an OBD 1 ecu and it plugs right up.

yep thats your best bet

ok the wiring is fixed and the new code that came up is P0420(catalyst below threshold). why in the hell is this coming up? the catalytic convertor is fine. this racer chick i know up at autozone(only person ive ever seen at autozone that knows what the fuck they are talkin bout) said that she gets that code every now and then. she said she just pulls out both o2 sensors and cleans them with gas and break cleaner and its fine for a while. shes got a h22a prelude if thats any help. but hey no o2 sensor wiring problems, yay! im still confused about the a/c compressor goin haywire though, any clues?

I just got that same code on my 98 ex, d16y8, the po420, and I can't find anything wrong with it. I checked both o2 sensors too, but mine doesn't run real rich or anything. Don't know why the a/c compressor would be acting up, though.

that code is because your secondary o2 sensor is telling your computer that your cat is no good...

i just installed a brand new hi-flow cat 2 weeks ago

you shouldnt be smellin a cloud of gas when you stop when running pump gas.

Unless you raised your compression, 87 is still the best thing for your car.

lacuna you didnt read that right. its not runnin rich anymore, cuz i fixed my wiring for the o2 sensor. now its throwing the code for bad cat. im runnin 87 in it, it was just runnin rich cuz it wasnt reading the second o2 sensor. should i pull both of my o2 sensors out and clean them, or get new ones?????

If you need another O2 sensor let me know i have a few of them laying around. I can hook you up cheap. PM me.

Mmm looks to me like you wrote it wrong. But either way your on pump gas, so my previous post was irrelevant. Sorry.

If your second O2 sensor is not getting a reading at all I would check the wiring first. Cleaning it wouldn't hurt but a dirty sensor is more likely to cause a bad reading than no reading at all.
