Default Fuel loss and hesitation

If I'm at a steady speed, then give it some gas, the signal momentarily on my A/F gauge drops off the lean end, accompanied with momentary hesitation (that has been plaguing me for a while now), then the fuel catches up and seems to run properly. What'* the deal with that? It happens from a stop, also.

Hows the fuel filter?
Maybe your strainer and fuel pump are starting to fade?

Fuel filter is less than two years old.

I've been considering the pump and strainer for a while now. I've got the classic 92 problem.

Allot can happen in 2 years. I know that you usually don't have to change them very often but I have had mine changed twice in just a few months, ( long story).

With all the crap in the gas these days it may just be that.

Usually the fuel pump issues is more prominent when turning sharp?
The fuel filter could be suspect if the tank is old and cruddy.

Seriously though, since it happens when you step on it it coudl either be that fuel filter but could also be the sock in the tank or both. I would get the fule filter changed first and go from there. I have had filters do strange things on me before.

Besides it is the cheapest fix, and most of the time the cheapest fix is what was wrong ( not in my case ever though)

Do I need a GM filter, or can I get some other brand from Autozone or NAPA?

the fuel filter isn't a GM part only, you can get it from any parts store. I got mine from autozone.

I was asking if anyone thought an off-brand gave off-results.

For the fuel filter, I use whatever they have, wherever I go. I would only buy a name-brand if I wanted it to sound cool. Like the PCV.

Imagine what my sig would look like.

I agree. Fuel filter for 5 bucks, if that doesn't do it, go after the pump/strainer. Sounds like you have another excuse to do that anyway. But before you do the extreme (tank drop) check your fuel pressure by the book.
