my car stumbles under light pressure to the gas pedal, but still feels as fast as ever under wot.

the stumbling feels similar to the feeling of running really low on gas

 

I had the same problem, I changed the plugs to NGK TR55 GP's and now it runs like a champ!

so i should check my plugs?

 

my msd stopped working a little while ago, so i have been on the stock setup. iwonder if the msd going out was actually an early warning that my plugs were going out. anyway, if the plugs are the problem,do you think my msd will start working again after changing them?

 

Um, yea if that was the problem. If your ignition is great up to your plugs and then your plugs screw up, then you wouldnt know if the MSD was to blame. I say change the plugs, then try both ignitions and find out if one of those are the problem. Plugs are cheap too.

How do you like you SLP headers, I may be getting some, Gains?

well i know my car surprises alot of people, and i think they are to blame, but i bought the car with them already on so i dont know about gains
