12 DEG BEN 0 Posted May 28, 2008 You can tell them apart by looking at the hole where the throttle body goes at the back of the manifold. OBD1 ones have a tube coming out of the manifold on the expansion tank side for the idle control gubbins. OBD2 does not as the idle is sorted by the trottle body itself.
