yeah let us know what they charging

And what is your car doing that you think the ECM is the problem?

Re: 1990 ZR1 ECM Needed
 

It has an intermittent misfire. It runs great and then it loses a cylinder. I replaced the ignition module first and all injectors plugs and wires. Still did it, so I pulled the ECM and had it run in another ZR1 with no problems and it duplicated the misfire after about 10 mins of running. Sure hope this is the problem.

I had a very sililar problem some years ago. In my case it was caused by me back probing the injector pins at the ECM plug. Big no no.
