95 gt hiccuping

[jedpony]

My 95 gt has developed a problem. It runs perfectly fine when I first drive it but after the first few min of driving it starts to hesitate when I give it a good amount if gas. It will hiccup and hesitate and have no power. Hard to explaine. Would this be my o2 sensors going bad and in need of being replaced? Car has just over 100k miles. Just changed the plugs wires and cap and rotor a few months ago.

id assume o2 sensors...runs fine until they warm up and are sapose to adjust better....

could be O2's. they are definately due for replacement. But it's sounding more like the distributor. or more precisely the PIP inside the dizzy.
Are there any other mods to the motor?
have you pulled codes? you can have one set without the CEL being on

So the check engine light doesnt always come on if i have a bad o2 sensor?. The Dizzy? sorry im not used to the distributer world yet. Does that have anything to do with the cap and rotor? I replaced it a few months ago with a msd cap and rotor with ford racing 9 mm wires and ford motorcraft copper plugs. Other mods that i know of are just k&n filter, full exhaust, no cats, underdrive pullies.

had the same issues with mine and a TPS replacement fixed it all.

Dizzy is slang for distributor which is the main part that the cap and rotor attach to. A brief and simple description of it is a shaft is spun by the cam at the bottom of the dizzy. At top of shaft is the rotor. As it spins current sent through the rotor jumps to the points inside the cap and then go through wire to plugs. There are a few other parts inside the dizzy that do more but, I can't explain that much technical.
