The ECU is under either the drivers seat or passengers. You can't miss it...it's a big hunk of metal. Also check the ground wire going from the body to the engine...it's on the drivers side..I think. It's a big braided bit of copper.
I've owned one of these for a few years back in the late 80's. Very fun car...and yes...$$$ to fix if it went wrong on you.
