PROBLEM WITH MY 1994 Q45

[troyb17]

I have a 1994 Infiniti Q45 with 121000 miles on it.I notice that it bucks and jerks when driving and it also deaccelerates when im pushing down on the gas pedal when im on the highway.I got a diagnostic from Nissan and they told me that the problem MIGHT be the MAF.I actually got a brand new MAF and the problem actually got worse.So Im stuck right now I know that I do here some humming from the trunk like a swarm of bees but Im thinking if i get the fuel pump replaced will that solve the bucking jerking and the sluggish deaccleration.Im just tired of putting money out and I dont know what the problem is.I just put out $100 for the diagnostic and that was a waste.Please help and thanks.

The fuel pump could fix it, but you gotta fix it regardless.... Otherwise it will completely fail and knock oiut your fuel pump controller...

REPLACE THE PUMP and i think it should fix it.
