YACT: Help me diagnose acceleration stuttering

In the past month my '92 Toyota Corolla with 110,000 on it has had a problem accelerating twice.

There's no problem starting but when I try to accelerate from a stop, the car stutters, like it's not getting gas. If I drive it a while it resolves itself.

It's never had a tune up that I know of, could it be a spark problem?
 
I'm no expert, but it defintiely sounds like either a spark plug or a fuel filter issue. Plugs are simple to replace, so try that first, replacing plugs and wires. I've never done a fuel filter replacement, but it seems like something that could be done yourself.
 
Start throwing some maintenance parts at it. Filters, wires, plugs... No harm in doing that, since it may take care of it, and you have to do it anyway. That will save the money of having a mechanic do the same.
 
It's not getting enough gas, probably because of old worn valves or any part of the injection system. Without examining it nobody can say for sure though.

It is highly unlikely that it is a spark problem if you get no misfires or knocking from it.
 
I'd start with the plugs, then move onto fuel filter, like they said above. The fuel filter can be tricky depending on where it is. The biggest problem is if the hoses are rusted on.

That is good advice.

You'll probably want to change those old hoses anyways, high chance it needs to be replaced after the fact as just a bit of twisting on them could lead to a leak in the future. Premeasure the hoses and buy them beforehand. Fuel lines are expensive so don't buy a length too long.

Unfortunately I'll have to learn this crap. This car has to last me another 5 years. What's worse is my wife drives a '98 Dodge Neon which has to last the same, and I anticipate it will have MUCH MORE severe problems than my little Corolla.
 
I'm actually replacing the distributor cap/plug leads on my 90 Camry right now, for pretty much the symptoms you describe. All it really needs is a plug cap (the connector is busted inside) but you can't buy just the cap, or even a set of wires.

Ornery's advice is good.
