90 240 flickering Check Engine light 1990

I just got a 90 240 sedan and after an initial tune up of dist cap and rotor and the correct spark plugs, it still seems to start rough, but run fine. I put another spedometer unit in it, (the old one was non functional) and the check engine light fleckers at idle, but comes on brightly at higher revs! No codes are set in the computer. This car looks like it had a rough past life, and I suspect that the reason I got it so cheap is becaus it won't pass emissions up-state. (My county doesn't have emissions inspections)

You might want to post this problem in the 240 section of the board, this one is for front wheel drivers.
Did the CEL flicker before you changed out the speedo? If not, then you probably have a bad connection in the instrument cluster.
If it always flickered, then you have a bad ground wire somewhere. Probably on the driver's side fender.
