Default how do i test my 1991 acura integra ecu?

I have all the classic symptoms of ecu failure but I want to make sure before I buy a new one. How can I test it without replacing everything that it might be first? Process of elimination can be very expensive!!

What you need to do is buy the Acura factory service manual from www.helminc.comOnce you have that manual, you can test all the inputs/outputs from the computer and during the testing, your results will tell you whether it is the computer or a series of failures from inputs outputs etc.Otherwise, you might just want to go to a junk yard and see if you can pull or buy a used ECU that matches the codes on the one in your car. Even the junk yard might give you a small warranty period on the ECU but I'm betting that it wouldn't cost all that much considering the time it's going to take to test all the inputs/outputs.
