I am having a problem that seems to happen around half throttle.  It doesn't matter what the RPMS are at.  When i go to half throttle or higher the motor seems to cut in and out really bad, it seems like its missfiring.  If i rev the motor out of gear it oesn't appear to do it that bad.  I tried driving it at full throttle in 4th gear at a low speed and it cuts in and out even at really low RPMS.  It starts to happen really bad at around 2 psi.

I really don't know where to start so if anybody could help me out i woul appreciate it.  Its an S13 redtop in a 91 240

Thanks
