My CHECK ENGINE light is on after installing the Helix Power Tower. Why?
A. Review all connections that may have been removed or disconnected during the installation. Make sure they are properly reconnected and correctly installed. If that is not the case, verify the mounting gasket correct position. Do all of the holes line-up against the throttle body and/or the Helix Power Tower? Recheck any and all vacuum lines that may have become disconnected during installation. Q.
