I just picked up a 94 hatch with a B18C1 and it's been running fine since I got it about a week ago. Now it's idling rough and stalls. Check engine light is on and I have a scanner but can't find the plug for it. I've looked under the steering wheel and behind the passenger side kick panel, but no luck. Any help would be greatly appreciated!!

 

Should be a green plug under or near your glove box with 2 plugs in it. 1 i believe 3 wire the other 2 wire.

On the 2 wire plug - Stick a paper clip connecting into each hole and turn ur key ONII position. Check engine light should appear.

 

Is it obd1 or 2? Its right under your glove box tho

 

Completely forgot about the paper clip lol. It was 1 long blink then 5 blinks and 9 blinks.

 

if its obd1 do what blackcivicex said, just look at the ecu code so we can tell you if its obd1 or 2

 

nvm seems like you figured it out now

 

intake air temperature sensor, map sensor, and no. 1 cylinder position

 

 

Thanks guys. Now just to figure out what the codes are?

 

Thanks!
