Stuttering while cruising

[KamiKaziDK]

While cruising the car at pretty much any speed, you can feel a stutter or miss almost. I figured it was the PiP going out so I swapped out my dizzy with a good one(out of a good running car) and still have the same problem. I'm gonna throw a new cap/rotor and wires on cause it needs to be done anyways, but does any one have any other ideas? Could my O2s cause this without throwing a code or the MAF sensor be going bad? Thanks for the input guys, hoping maybe someone has had this issue before and has a quick fix.

Yes could be the 02's

Yeah...they do have 160k miles on them.....ours are upstream, right?

lol, nm....was browsing posts and saw the one where the guy got the wrong sensor

There are only 2 O2 sensors and they are before the cats for our years (94-95 GT). Upstream is what you will want.

Not the O2 sensors, swapped in two new ones and nothing changed. Gonna clean my MAF and IAC and see if that helps next.

I recently had this problem and it turned out to be the MAF sensor plug not completely plugged in due to a broken clip. Put a new plug on and stuttering has been gone for a month and half. Worth a check

wore out plugs will do that, i would do a full tune up with a good maf cleaning

Did you pop off your negative cable, to clear out the EEC, so that it relearns the new sensors?

Has anyone fixed this problem yet?

Plugs, wires and cap and rotor are all new. I'll check the connector and clean the contacts cjr, see if that helps. I disconnect the battery every time I do something.
