'87 Integra Computer
 

'87 5-dr, A/C, automatic trans.

Just wondering -- how do I verify that the computer is working? The 'check engine' (PGM/FI, whatever) light on the dash is not on ... yeah, I'll be checking the bulb!

But when I turn the key and observe the LED on the ECU, nothing. If there are no error codes set, would the thing simply not blink at all?

It's not running its best, either ... sometimes it almost feels like it's dropped into Closed Loop mode. Not good. :eek:

Welll, thanks in advance! Any tips or thoughts are appreciated.
