yet another issue with the '96 Caravan...

I swear I'm gonna blow this thing up... Same 1996 3.3L caravan that I
replaced the fuel pump on and mysterious tensioner issues.

Last night while coming home from work I noticed the engine started
making a knocking sound. I'm not sure what rod knock sounds like, or
even what causes it, but this may be it.

I only hear the "knocking" sound when I accellerate. If I'm idling, or
if I'm cruising under 1500-2000rpm, I don't hear it. If I have to
accellerate even mildly from a light, I hear it.


I know thie description is vague, but if anyone can help with this it
would be appreciated.
