I recently bought a 1988 subaru gl wagon 3at 4wd just did a tune up. It has a rattle it gets after running for a little bit. It will only rattle when I throttle but coasting is just fine does anyone have an idea what it could be?

 

Also does anyone know how big of tires I can put at stock height with out rubbing or having to cut my fenders? I'm trying to find wheels and tires for it as well.

The "has a little rattle" is a little vague but I'd check the timing. Could be too far advanced. 

When I start it up and drive it doesn't rattle but after driving a bit it rattles only when pressing on the gas.
