Hey Guys,
Sorry to post off topic but I cant find help anywhere else. My brothers '04 cavalier is hesitating upon accelerating. When you depress the gas from a stop the car seems like its loosing spark (or perhaps fuel?), the car usually picks right back up with no porblem, sometimes it stalls. When accelerating from a roll there are no problems. If you ease into the gas it works ok. Car is idling very smooth, running very smooth, no CEL's or other problems. He's using NGK V-Powers gapped at 35 (switched because he runs N2O at the track). Any ideas? Should the plugs be gapped closer to 30? This problem didnt start until we switched from OEM plugs to the NGK's so Im leaning that direction. Any other ideas?

Thanks!

If it's doing it after the swap, could be sparks or wires. Make sure they are firmly locked in.

Well, I think that me be part of the issue, that car dosent actually have plug wires, it has a module that bolts onto the valve cover and connects onto the spark plugs. Now when I replaced this device I couldnt get the spark plug boots to "click" like regular wires do, best I could figgure is when you rebolted this thing down it seated the plug boots properly, but that may not be the case.
