 Steve, I have a '95, but I still have the same sensors as you. (1)--have
the TPS(throttle position sensor replaced). I might be not good enough to
work but good enough to not throw a code and will lead to scratching of the
head and headaches. The pinging will be from the sensors also, in that it
tells the computer how much fuel to give the engine. At least have all the
throttle body sensors checked to determine which one isn't within tolerance
of a certain voltage. The TPS sensor should be on the side of the TB and
there's a AIS(don't remember the name of this sensor, but it's on the back
side of the TB and it ALWAYS gets gummed up with carbon that needs to be
cleaned out and there's the MAP sensor on the front of the TB that's is
vaccuum and voltage operated. Have these sensors checked out--you'll
probably find your problem.
2)--Cats aren't suppose to smell at all. Having the engine running bad is
what is causing the problem. You might have to have the cat replaced,
because it's probably going through melt-down. If it smells like rotten
eggs--definitely needs replacing.
3) adjusting the throttle kick-down wire to the tranny will ease up on the
banging in reverse. Sometimes Mopars have a curse with this problem. It
doesn't hurt the tranny, I've had a problem with the same banging in an old
'68 barracuda. Hasn't hurt the tranny yet. I think that the problem lies
inside the tranny itself--by having a larger hole drilled in the reversing
side of valve body and with a good working tranny pump it has more pressure.
Anyway try the wire adjustment.
4)--can't help with the brakes--maybe could be that the calipers or rear
brake wheel cylinders aren't releasing all the way. Could also be the wheel
porportiting valve isn't adjusted correct.
