will let you know what the cel is for as soon as i can plug it in. till then i'm ridin dirty on a 10 day inspection sticker.

 

^^ Then wash your car. Otherwise, ridin' dirty doesn't make sense to me. haha

 

you can jump the ecu and read the codes yourself you dont have to have a obd scanner,

p1337, p0141, p0450. The monitors that are incomplete are evap, o2, and cat.
keep in mind it's a 97 honda civic (obd2) with a 99 gsr motor (obd2) running off a obd1 ecu. body harness is what was on the 97, not swapped. i know that there are 2 o2 sensors in both cars, 97 sensor are in the manifold and in cat, 99 gsr one in the cat and one in the pipe before the cat. so.....yeah.any takers.

 

Unbolt one flange and check that you really have a cat, not a hollow shell. The evap code is typically the gas cap but it could be a leak anywhere. Make sure the canister, solenoid, hoses etc. are properly plumbed.

 

x2 on checking if it's actually a cat

 

waiting on a new muffler, have it in the air when that gets here in a couple days, find out then and post when i got news. thanks for all the feedback.

 

so a few things have happened since its been a while.
1. got a sticker good till 1/11! me-1, car-0
2. got the new muffler put on and its amazing sounding, so angry! me-2, car-0
3. the f*!king clutch is going! AHHH! me-2, car-1
4. having new Exedy stage 1 and 8.5lb comp clutch flywheel put in on thursday! me-3, car-who cares, stage one and ultra lightweight flywheel! yeah!

 

Looking back at this, OBD1 systems don't have 4 digit codes. You have some sort of OBDII ECU. I think you are talking about OBDIIa vs OBDIIb, not OBD1.

 

i am running a obd2 to obd1 ecu, car and motor are obd2. in order to pass inspection i bought an obd2 computer and the codes i got after clearing and plugging it in were what i had posted. got a sticker now, so running off the tuned obd1 full time.
