Default Hiccup

Recently my car (02 2.5 RS) has started hiccuping. At idle, every few seconds there is a studder or hiccup and you can feel the car shake for a second. Once and a while under acceleration it will do it also. I thought maybe it was bad gas, but I filled up today, differnt station and same thing. No CEL's or anything. I am really confused as to what this can be, anyone have any ideas?

Thanks

I'd check the coil pack, look for corrosion.

When was the last time you changed the fuel filter?

Two good places to start.

Default Mine too

Mine does the same thing but I have 2.5d and 1.8 ecu with bigger exhaust. My plug wires appear to be original and the coilpack measured fine. I also swapped coilpack with my other from the 1.8 and the same hiccup. I have one month old NGK plugs. Where is the best place to get plug wires for the dohc other than the dealer? I don't want to get some generic "super spark" or "sparkarama" from Hilo or autozone, etc..

My car hiccups after every fill up. People say it is probably due to the sediment in the fuel tank being stirred up I'm not sure. Still happens, but it was a lot more like a buck before I swapped out my fuel filter.

Was thinking. May even be, ever so slightly, the A/F sensor (or front oxygen sensor). How has your mileage been? If its still ok then your mileage shouldn't be effected too much.
