When I take off from a traffic light at full throttle in first gear everything is fine. When my car shifts into second and I am at full boost my car starts to sputter almost like its hitting a rev limiter. What could this be? Could my spark plugs be shot? When I am driving at normal speeds and not at full throttle the car seems to run fine. Any help would be greatly appreciated.

Are you letting your car warm up completely before you get on it and are you running a different heat range plug?

This happens no matter how long my car has been running. I never get on it unless the car is totally warmed up. I am using the NGK 3330's.

I had this same problem a couple of times. Sometimes it did it, sometimes it didn't. My car is ripped apart now so I can't help you very much, but I would say change your plugs. How many miles do you have on them. 3330's only last about every other oil change.

i don't like to use the NGK3330. I feel the NGK6097 works better with our car. Just my 2 cents.

Do the NGK 6097's last longer than the 3330's?

from my experence the 3330 gives you rough idle but not the 6097. i need to change my 3330 about 4000 miles. the 6097 ran longer than the 3330.
