ok heres the deal, a friend of mine just bought a Gsr

last night we drive it after we put a header on(which would not cause this) it would mis at light throttle, basically it wouldnt go past 3,000rpm

now my car has been doin that intermittantly for a few months now since i put in my new engine....

now the only thing i can see that is the same on both cars at first glance was that we both had an MSD Dist. cap and External coil....

but i removed mine seeing if that was the problem and it didnt fix it soo maybe my problem is something else....

but it is very similar

the only other thing i can think of is that he broke the ground wire goin from the vavle cover to the frame(he was alittle to rough) but he just crushed the strands of wire under the bolt...soo that should work for the time being.....

was wondering if anyone else has seen this problem and fixed it......

Neither of us are getting CEL's so its frustrating
