Or you can try changing the ECU?.

 

I've bought 3 different ecu's already so I have no clue

 

I too have been having a problem with a code 13 on a buddies integra, though my scenario is a little different. We just put a turbo kit on it last weekend. We finally got it tuned to the point that we can drive it. (pretty sad...don't buy an ebay kit unless you know what you are doing) So it seems that we are only getting a code when we end up giving the motor boost. The odd part is that it is intermittent for when the light actually comes on. I was hoping that it was going to be as simple as putting a different map sensor on it, but it doesn't seem like it will be that easy if the BARO sensor is in the ecm. We were planning on trying to put a GM 3bar map sensor in, though yet again, im not too sure if this will solve our problem.

On another note, the whole incident with your emissions test....The car runs fine untill that light comes on...and then the car just dumps fuel. Even just drivnig it nice down the highway. It goes all the way up to 10.0 on the air/fuel (rich) and it won't try to compensate when we give it gas. It goes into like a default, where it won't give it any more fuel when we give it more throttle, which then makes it go all the way lean at like 17.4. So that would be your emissions problem, especially for cali.

 

Yea I had a feeling that the ECM MIL code was the reason it failed smog. I have yet to locate a resonably priced ecm that I can see running in another car without a code 13 on it. I'm pretty sure at this point from everyone I have talked to that code 13=bad ECM. If you buy the map sensor it won't fix the problem, tried the same thing and didn't work.

 

Turbo kits are awsome, just go pay to get it tuned if you don't know what you are doing. that's what I did and it was great.

 

well, turbo worked out great, got it tuned, though he wrecked it on thurs, so we put the motor in a EG hatch!

 

So I found an ECM in a car bought it watched it run no MILL lights, and I put it into my car and the MIL light comes on still? Can someone who has a 5sp 91 integra take a picture of their wiring harness so that I can see if mine is maybe missing the wire for the baro switch. The following sentence is speculation. Maybe the car is supposes to be wired for the BARO sensor to recieve information, and that wire is missing on my harness? I think that maybe the wire that should be there is missing. So I need pictures that are highly desriptive so I can compare to mine. That way I know if there is supposed to be a wire goignt o the pin on the ecu
