97 Z24 sputtering
Tuesday, July 26, 2011 2:58 PM
97 z24, 2.4, 5 speed, etc...

Sometimes when I come to a stop the car will sputter horribly and occasionally stall... The idle jumps around before it does.

Then, sometimes after that happens or separately, if I press on the gas to start moving the car will just sputter and not accelerate willingly even if I floor it. If I let off the gas the problem stops.

I searched high and low but couldn't find a straight answer.

I'm having the same problem... don't have any idea what it is, but I am going to listen for answers.

without actually being there to see exactly what the car is doing, its ahrd to tell. my first impression is maybe coil packs/housing, plugs, or ignition control module. I had a similar problem a few months back. "Random Misfire" was the code I got. My suggestion is maybe go to Auto Zone or Advance Auto and see if there are any codes. Then start looking at spark, fuel, air, or fire. I imagine it would be one of those issues. Hope this was a help

The plugs only have a few thousand miles on them. I also replaced the plug connectors.

The guy I bought it from thought it was the injectors, but I swapped them out with another set and the problem persisted.

It seems like when the car bogs down during acceleration, if I REALLY lightly increase throttle percentage it will start to accelerate... vs if I just hammer the gas and it hesitates.

Sounds like the coil housing. Do a swap to regular coils and plug wires. There are a few write ups about it.

I was actually just reading about that. I may give it a shot.

Let me know how it turns out. I haven't gotten around to doing it yet.
