When should I have the plugs changed?

[ricamryman]

When my car had 106 K miles I had the plugs changed out with new wires,cap,& rotor! I am at 147K miles now. When do I need to change the plugs again? Its a 1993 3VZFE V6 engine. ......

Depends on the metal of the tip. If you're really concerned, you can take them out to see how 'dirty' the electrodes are in order to check for any other problems and also check the gaps. Also, check to see if your gas mileage has dropped (poor indicator). Most likely, you're fine.

Hey bdy0003, I see you are in the worst half of Ca.
What half is that... me, I'm in SoCal.

IIRC, the manual recommends 100k miles intervals, assuming platinum plugs are used. So you're probably good for a while yet. If you don't know what plugs are in it, pull one out of the front bank to check; they're easy-peasy to get out.
