In fact i have problem with the solenoide M/C, the shop manual says ECM fault.
is it possible to find a new ECM ?
do you know suppliers for that ?

I guess you don't have a NAPA in France, but you could try Napaonline.com

Are you using the 1981 Corvette Shop Manual from Chevrolet or some other shop manual?

Is the Check Engine light on?

The "solenoide M/C" is probably the M/C solenoid and "M/C" stands for mixture control solenoid. That's the solenoid that controls the primary metering rods and sets part throttle fuel mixture.

You may or may not need a new ECM. You also may or maynot need to replace the M/C solenoid.

Without additional information it's tough to say which.

But, regardless of what the problem is, in France it's going to be difficult to get parts. I'd make sure of your diagnosis before you order parts.
