pinging b/w 3K-4K rpms + old matress noise in suspension
I've recently noticed a pinging type noise when I accelerate b/w 3K and 4K rpms, kinda sounds metallic. I always use 93 in my Max and had a tune-up done last year at 106K, currently at 128.3K. What can be the cause of the ping?
2nd, I performed a bounce-test on my Max, there's an old-matress type noise coming from the front area, this happens even when I get into my Max. I can also hear it going over bumps. What can cause the "old-matress" syndrome?

the old matress sound COULD be your seat....mine does it if the lumbar is up
as for the pinging... - how loud is it?
are you 5spd or auto?
cant you leave it parked...rev it up and hear it? or is it ONLY while driving?
