MAC11 update

[Ben Swann]

Rick we presume has replaced at this point all spark plugs, distributor cap, rotor and
coil as well as the wires - at least once  If not, it would be a good idea just to rule
any/all this out.  Indeed any of these components can cause these symptoms - cap and
rotor in particular.

I'm late to the conversation...has anyone suggested the dist cap.....I recall having a
similar problem and after chasing everything down discovered a very small crack inside
the distg cap.....

Second that remark - signaling to the coil might be correct, but that amplifier does
require a good ground as does the coil.  I invariably put them all into one common point
that tie together in a standoff post on firewall with at least #6 wire running back to
the battery post - even if the car is a giant ground strap itself.

You will also want to examine the positive feed to ECU - I noted some of the "stock"
wiring to be seemingly marginal to support a load of a coil, yet seems all goes through
the ECU - with possible exception of the coil positive feed itself  - I forget how that
is, but may be something to check.   However, typical coil feed breakdown would occur at
more like 7000 RPM, not at 2K I'd think.

Still I believe it to be something else than ignition.   [snip]
