Hi All,
I've got an '89 with the 4.2 and dreaded Carter carb. Previous owner
paid a small fortune to get is to pass local emmision tests, then
decided to sell it.

Occasionally, it would not start after a short trip. Engine would turn
over fine but no spark at the coil. Thanks to this newsgroup I ended up
changing the coil and then the ignition module. This problem seems to
have gone away... I haven't had to walk home for some time.

Now I have an intermittent miss. When it happens the tachometer drops
to zero. Vehicle act as though the ignition has been shut off.
Sometimes this will be only for a millisecond or so, and sometimes two
or three seconds. I have been looking for a loose connector, frayed
wire, shorting wire, etc. And having no luck yet. Does someone have any
suggestions on what I may have wrong?
