Full disclosure:
I purchased this used from a local user, sat around a while till my car started running again. Paid the shop to install this ecu and they could not get my car to idle without the ecu cutting out and losing power momentarily.
Decided to just run my car with the stock ecu and I'm looking to sell this now..

I was going to send to DIY for diagnosis but decided against it.
My buddy opened this up for me and said it looks good to him.

It's a 94-95 MSPNP1.
I'm letting this go for $325 shipped.
