86 XT GL Coupe - Lurching

[JonnieBlue]

Okay.. here are some questions..

what causes this feeling of 'lurching' or jumping forward? It almost always
happens in low gear (i get really crappy low gear preformance at like 10 -
25 mph) and now started happening in higher gears while keeping steady on
the accelerator.

next - i checked my Man. Trans. Lub. level a few mos ago, was at right
height ondipstick but appeared 'bubbly', checked it today it was at
completely low line (very bottom line).. what caused it to run out so much?

- i dont know if this is related, but the spark plugs appeared to be running
hot (plugs were white), and one of the metal connector harness things inside
the rubber boot was rusted all over, but the other wires were fine.. what do
i need to do about this?

finally - when im driving, there is a very coins in a can like sound, can be
affected by the accelerator, but not completely dependent on it.. it is
becomming more common of a condition.. when the car is running (idling) and
i listen at the back near the exhaust, it sounds like (best i can describe
it) a boat running - no smooth operation sounds, but kind of a low soft
'boam boam boam' continuously


Sry for the large amount of questions, but they all apear to have come up at
the same time - i noticed the noises and checked it over:
air filter fine, distr fine and not moveable, plugs were a bit white, wires
fine (except rusted one), fuel filter changed, belts are fine, fluids are
fine when i add to them, battery and alt are all fine, distr isnt cracked or
anything...

any help appreciated

check the 'old generation forum' on the message bds. at www.usmb.net for
good help with older soobs. Of course, monitor here as well. I'm
wondering if the coins in a can noise could be exhaust heat shields
rattling.

Basically I would replace all the plugs and leads for starters. I have
a feeling that coins in the can noise is pinging. Try running a higher
octane fuel. I'm not sure what would cause the oil to be bubbly in the
trans, it could be really old oil which is due to be replaced
(antibubbling agents in the oil could be passed the use-by date so to
speak).
