if i remember have someone rev the engine past 3250 rpms. There are 2 black cables that run into the back of the intake manifold. at 3250 rpms, those cables should jump/move. If they aren't, the IMRC's are not working.
Did you mean to put 1516? because he put 1518.

Either way what you should do is the same, see if the cables are moving.
