Hi!
I've observed the symptom, that the ignition coil is hot when working. It's
good or something is wrong??
 
There is quite a lot of power used by the coil when working which will make
it get hot under normal running conditions. When you can fry an egg on it
then it is too hot. Check all connections to/from the coil and ignition
amplifier. You will be looking for very good connections with no corrosion
and as low resistance as possible. This will eliminate sources of over
heating of the coil if you are worried about it. Sometimes the earth
(ground) connections can cause overheating by being a bit dirty. As I said
yesterday, the car looks very good, Jarek.

All the best, Peter.

OK,. I check it. The coil is hot,..very hot.
The car looks so good :) but I've fighted with this engine,..the mechanics
haven't got any idea of bed working. But I've obssereved, that sometimes the
engine, works so good,..the RPM is good, the acceleration and power is OK,
anything is good,..but some days engine woorks so bad. The more noisy, lost
the power, acceleration is no good. (when the temperature of air is hot,
when day is sunny, engine works very good!).

And I don't know why engine, for example one day works very good,..but next
three days engine works so bed. May be the coil is so hot and bad
working,..may by my IACV works bad (Do IACV give some symtomps in normal
driving if it's broken,..or only give symptoms on Idle speed??).

I don't know,...help me! :))

all the best...

Tell me,..The coil and amplifire can be broke "a little" ?? or if it's
broken, the engine in 100% wille be not working?

How can I check,that the coil and amplifire is good or not?

How hot is hot? I can't tell from here, but coils to get warm while in
use. Chances are it's OK, but what you need to do is find a similar
car, and see if the coil is roughly the same temperature.
