It Starts OKish but idle misses. It has been doing that for a while then all of a sudden this happened. I have been running with lower than usual fuel level lately but it was above 1/4 when this started to happen. The reason I think it is electrical breakdown is because that is the only thing that ever went wrong with my E12 (man I miss that car)
Anyway thanks for any advice


Matt,

One cylinder maybe, more than one I doubt it.
Does the engine crank over and idle OK? IF yes,
I doubt leads are the problem. Maybe a coil wire
or coil, but spark kv is higher during cranking
(rule of thumb is 1kv per 10 psi compression) than
at idle or cruise. I'd be more worried about
something other than ignition, like fuel pressure/
volume, false air, or Motronic input (like VAF).

Is the engine running OK today? Could the fuel
level be low (or lower than usual) in the tank?

Just a few thoughts...

Randy
