1993 SC400 running on 4 cylinders?
I know there are a lot of these no start or running issue threads. I recently bought a non running SC400 and using some of these old threads at least got it so start.
Now the issue I have is it is “running” but not really. It sounds terrible.
I pulled the wires from each coil to the distributor at different times and it didn’t change the sound of anything.
Just wondering where to go to go next to look. Ecu? Seems like a lot of people have to get them rebuilt.
I will try to attach a video of it running. Also no codes stored.
i couldn’t get the video to embed so there is the link.

Have you checked the coil wires themselves? When i lost 4 cyls in my 93 it was because the coil wire had shorted under the distributor cover where i couldnt see it without disassembly.
