Bought this car from original owner, was serviced regular, well kept. It has (all at once) developed a slight" bumping". The tach would INCREASE about 300 rpm's. Local dealership wanted to install a new trans....$2400.00 !!!!! NOT.......I changed plugs and wires. NOW the increase in RPM's is only around 100 or so...so this HEPLED whatever the problem is...What is the problem ?

Has the fuel system been checked? Try some fuel system cleaner and see if that helps.
