When I accelerate even slightly in my '94 XL I hear a chirping sound.
Like a bird. It goes away immediately when I ease off the accelerator
pedal. Doesn't affect performance, just annoying and maybe something on
it's way out? Any ideas/suggestions appreciated. thanks.
Very interesting that this appears next to the belt tensioner. In my 97
the chirping sound went away when I replaced the belt tensioner.

Yeah, I suspect the tensioner but I replaced it about 30,000 miles ago
(when the truck had about 40,000 miles on it). Do these things typically
have a short life span?

i had a similar noise i eventually found coming from near the firewall.
i ran engine without serpentine belt to eliminate all that stuff. turned
out to be camshaft synchronizer.

Thanks. I'll look into that. Is it hard to replace? expensive?

Remove your serpantine belt and see if the noise is still there. If so, it
is likely the camshaft synchronizer. I had the issue on my 97 OHV 4.0.
Itcan be a pain to replace depending on your engine. I had to remove the
upper & lower intake manifold to get to it on mine. Look up the thread
titled "Chirping 97 explorer " using google groups.
