Just out of couriosity. is it normal for the RPM`s to go between 1500 and 2000 a few times after you pull the fuse or pull off the negative battery connection? i know it`s not much of a 'tech' question, but I`m just wondering.

 

Stock 95 Civic?

Why did you reset the ECU?

There can be a brief idle relearn period after resetting the ECU, but it tends to be a low idle issue.

 

I have a short ram intake and a cheap Ebay catback on it, so not really stock. I did it since I installed foglights and the myth that you have to reset the ecu if put in a new exhaust? It does it about 4 or 5 times than it idles normal, and the cel is not on. And I believe that an auto D16Z6 has an idle of 600 +-50.

 

How much driving have you done since the reset?

Try bleeding the cooling system and cleaning the IACV.

 

I`ve only driven about 10 miles on it. But I did miss one little bit of detail, it only happened once, and that`s when I started the car after I reset the ECU. The other starts after that, has no hunting idle and slows as the car warms up.

 

If the idle is back to normal now, don't worry about it unless the problem returns.

 

you dont need to reset the ECU with exhaust... the ecu is forever learning and will cut fuel delivery as needed. Thats just an old wifes tail...

 

The ECU will relearn, if there was a problem before typically it will come back just make take a day or so.
