out of the blue when i was driving my car started to surge and and it doesnt rev, it breaks up around 3000 and just doesnt sound like it should, its not deep and throaty no more, it surges when i drive it and when i rev it in park it just doesnt have it, what could it be, fuel pump????

 

have you tried trouble shooting it any? that might be a good place to start. any codes? is the tune up good? how about fuel preasure and the cat?

 

it was the fuel pump, would 80 gph be enough for my setup

 

i put the fuel pump on and it still does the same thing. when i squirt starting fluid down the carb it revs up and runs better, does it need a new carb?

 

fire it up in the dark and look under the hood. see if your coil is leaking. or other ign stuff.

could be a sign for a new tune up.

a 79 305 and my 86 2.8 have both done that, acting up for no reason.

It was not the coil but just needing a *** tune up, even when it was not time for a tune up. on the 79 I changed everything and then thrw in some cheap champion plugs and vroom vroom

 

I have a pretty similar problem on my bird, i changed plugs/cap/rotor/wires/o2 sensor most haven suggested a clogged cat. or restricted exhaust, i even done a fuel pressure check w/ the gauge which came up normal if you figure it out please let me know what it was.

 

it was my carb, it was clogged with somethin i guess cuz i put a new one on and it was fine.
