I beleive all OBD1 hondas use the same method to check CEL's try this thread here... https://www.honda-acura.net/forums/s...d.php?t=185065
It's even got a video showing you how. Also check the Integra FAQ thread in this forum, and the online resources thread in the civic/del-sol/el forum for info.
Once you know the code post it up, and we'll take it from there..
