Ok, so my car has had this problem REPEATEDLY!!! For the most part sporatically throughtout the powerband, I'm getting some major sputtering issues. Not to the point of feeling like a misfire, but like a hesitation. The only times it doesn't do it that much is at WOT. But otherwise it's happening all the time. I'm almost positive it's either ignition or fuel related. Its not a violent sputter, but it's so annoying and really really noticeable to the driver. It almost sounds like popcorn, if that makes any sense. Everytime I do something and the problem goes away but comes back like a month later. So far the things I've done have been:

1. Plugs
2. Wires
3. Fuel Filter
4. Ignitor
5. Tested another distributor
6. O2 Sensor
7. Checked CAM Timing
8. Checked Ignition Timing

Only other things I can think it might be is possibly fuel pump or injectors. I realize getting it dyno-tuned and them checking my air/fuel is something that needs to get done also, but I want to have this problem solved before I take it to get taken care of. Any other ideas to this would be great. I really dont know what else to do. I kind of planned to change my injectors anyways, but it was something I didn't want to just yet. I still have to get a few other things taken care of before that. Same with the fuel pump. Anyways, any help would be great. Thanks guys!

you need to explain the problem you are having if you want help

 

my bad, i got so caught up in the things that i fixed, i didn't put why i fixed them. But yeah, I edited the post so it's all there now.

 

ttt. . . any ideas guys?

 

If you have replaced your o2 sensor and your have replaced all the other things than you probley dont have enough spark to ignite your unburnt fuel.. or have you checked your timing belt... if your timing is off one tooth than your car will sputter and backfire... my car had the same problem...if not then you'll probley have to get better ignition

 

ok i'll try that. I have an ignition (MSD SCI) that i got from a friend for free a while ago. . So i guess now is as good a time as any to replace it. You dont think it is fuel related though? You dont think it could be injectors or the pump?

 

Make sure your crank timing is lined up with your cam timing at tdc and make sure ur ignition timing is at 16 degrees above top dead center
