When mine was running bad I pulled all the plugs (so it would turn over

easier) and used a spare plug with alligator clip.  Set the plug up where

you can see it.  Crank the engine.  Mine had very weak spark to 2

cylinders.  The coils were good.  After going through the enthusiast manual

for a whole week of troubleshooting it turned out to be an igniter.  As

Bill Cardell sugested, I found a club member willing to try my igniter in

his car.  Isolated the problem immediately.  Bill is a god.

| Well I took some advice last night and checked my fuel pressure regulator

(I

| will have to say that was the first time I have ever put my lips on a

Miata

| engine..glad I keep it clean!) it seemed to be ok, it holds under suction

from

| the intake side. Well it got me thinking again.. If the fuel pressure is

good

| then perhapse the spark is weak. I have just replaced the original plug

wires

| with NGK blues 5 or 6K miles ago. Here is my stupid question of the day:

since

| there is no distributer where would you check for weak spark? IE leaving

| unburned fuel, only firing in 2 or 3 cylinders..Help!

| 

| Thanks,
