ECM Question?

Hey Guy's, im thinking im gonna have to replace the ECM on my 97 TJ. I had a couple of good mechanics, friends, check this out, everything good up to computer, it wont give any info, 2.5 is running rough, mech's said the only way to fix is computer tell us where to go, and it won't. they said they had'nt had much luck with used computer's, so my question is, new or try used, sure someone has been here before,i posted this in general forum, but didnt get much response, Thanks.

I would only buy new. Sometiismes used work fine but sometimes they have issues. Ecu failure is really rare.

Ecu

The only reason im thinking the mechanics might be right about it is, a kid run it off in a pond, and maybe that did it, if this is the ECU that was on it at the time.

You gotta keep a sharp eye on them folks. I just finished a manual to auto swap and tried to install the new PCM from ACE. They put it in the case upside down which meant I had to cut their warranty labels and flip it around.

I did call them ahead of time telling them what I had to do and asked them to please put notes in the order file explaining what happened in case it ever needed to be shipped back.

They did apologize and said the notes would be in the file, so hopefully they did.
