I just swapped a B18a1 into my 90 hatch. When i turn it on in the mornings it idles high 3000 rpms. After it warms up it idles up and down between 1000 and 2000 rpms i am using a 91 integra ecu. The ecu is not throwing any codes so unsure what it is i have checked my vaccum lines they seem to be ok. Any help would be appreciated.
