[16v] Newbie (of sorts), with questions.

These probelms are typical of bad grounds. I would start there first.
Replace the main gound wire that attaches to the battery to the frame (by
the motor mount) and then to the transmission. While you are at it add one
that goes from the battery negative to the back of your maifold where there
should be a flat ground wire from the fire wall (near the coil) to the
manifold.
