What seems like aeons ago I bought a Silvertop 20V from a guy who had it in an 86.
The wiring was a bit of a mess but i got it in and running. But initially super rich.
After many months of dicking about with it, swapping out a number of sensors etc and its running a lot better but still a bit rich and just in neutral it stummbles a bit at 2500-3000 RPM and seems to limit at 4000RPM if you take it up slowly but you can work it past that point by kicking it or holding the right throttle opening.
Not getting any ECU codes unless I force them.
I've swapped out the AFM, changed to COPS, the ECU, the Knock sensor, the injectors, the spark plugs, the TPS.
Unpluging the water temp sensor doesnt throw a code, -I havent tried swapping that as I havent got another at the moment.
I'm starting to suspect the DLI converter it came with. (an unbranded thing in a diecast metal box like you would get from Dicksmith or Jaycar)
There are no names on the board or anything either.

In short, im over it, and just want to drive it before I let it go.
