93 Park Ave. Problem

I was sitting at the stop light and when the light changed I step on the gas pedal and it hesitated for 2 second like it was going to quit! I have used fuel injector cleaners. I haven't changed spark plugs for about a year now. I have changed my oil on a regular basis, changed out my water pump (what b*#!&) and thermostat, fuel filter. If your idling, and it does a sudden 'stall' any ideas what may be starting to failure? Anyone else exprience anything like this? Thanks

I haven't changed spark plugs for about a year now.

Therein lies the problem!

Sounds like maybe the wires are bad.

It's good policy to change the plugs and wires at the same time.

I changed plug wires about 2-3 years ago. Should they be replace again? Thanks
