Default 91 L98 Ecm

I am needing to find a new ECM for my car... It appears mines is faulty. i keep getting different awnsers, and need to know which one is right.... Does it matter if the old ECM came off of an auto or a manual transmission car? The service numbers on my ECM is: 16198260

thanks in advance!

I don't know if it matters for sure, but I think it does. O'rielly auto parts has these remanufactured for ~$75. If you don't have one in your area you can order from them online. Take your old one and there is a number on it, match it with the number on the Orielly computer, because they show like 3 of them when you input your make/model/year, all with different numbers for different applications.

The ECM itself is the same. The chip is a different part number though. I spoke with an ECM service / remanufacturing house once ... They told me that well over half of the returned "bad" ECMs were actually just bad chips or calpaks.

No there isnt.

What is the problem you are having?

The ECM is almost always the last answer to a SES code or running problem.
