Lately my 98 SVT has been driving weird. My RPM's kind of drop sometimes with the clutch in to the point where it occasionally stalls. Plus it feels a little powerless. Went to Autozone where they pulled the code P1518 (for free!!!)Intake Manifold Runner Control Stuck Open. The Haynes, or Chilton books dont discuss the IRMC at all (how to test, repair, replace) Does anyone know how to do this? Will this fix my RPM problem, the code and my slug SVT? Or is something else (IAC, MAF, etc..) possibly causing this problem and making the 1518 code come up? Thanks
