My car just started sputtering at low rpms and when I went to pass some on freeway and noticed it sputtered at high rpms in 2nd and 3rd gear about 7000rpms+

Anyone ever have this issue?

Maybe me coil pack bad? Or clutch slipping I'm new to the s2000 game I just payed my s2000 off so time to do mods or fix it up.

I just had a similar issue when I bought my S. it very well could be with the coil packs, it was on mine. You can go to your local shop and have them checked, or you can check them yourself. I couldn't tell ya how to do it off the top of my head. It is a fairly easy process.

other problems could be with fuel system, or your mapping sensor.

I had a 240sx that I had a similar problem with and it was the fuel injectors and the fuel rail.

 

Ok cool ill try these things in let u kno.
