Unhappy still backfiring!!!

ARGHHHH,
I replaced the bad vacuum lines, it made no difference, i checked the timming A ok.
What else could it be???
The backfing is not consistent and happens when giving gas not letting off.
it happens around 2200 to 3000.
I got a vacuum guage and it reads between 13-15
Someone said that it coudl be and exahuast leak??
HELP!!

Is it "backfiring"? or simply bucking?

Either way it might be the TPS.
