Hi guys im new to this site but have been reading on this problem that seem others have had but not sure if there is a true fix or what the issue is so heres my problem...


I bought a used 04 cobra with 50K miles on it. All stock ran perfect until i decided to change the plugs out. I bought a set of iridium plugs, put them in ran fine for a few days then all of a sudden starting to sputtering at WOT. Figured the plugs were bad so went and bougt a set of motorsports plugs from the dealer that was for MY car, put them in and still does the same damn thing! I even went and pulled the coils out cleaned them with a wire brush make sure there was good contact on the plug but still did not fix the issue.

So now im to the point that there may be a sensor that is not working correctly? I have no check engine light on, i have not had time to take it to a shop to see if they can do a diagnosis on it yet just FYI.

So plesae speak your mind nd shoot my ideas please.. now remember the car is stock the only mod when I BOUGHT IT was it has a drop in K&N filter.. ALSO KEEP IN MIND IT WAS RUNNING PERFECT TILL I CHANGED THE PLUGS but yet still does it.

crank position sensor, Cam sensor, O2 sensor or alternator???? These were the main things i have read... .

Well thx for the help if any for this newbie here i just want my damn snake to run so i can enjoy what i bought LOL!! :rolling:
