translate for me -My car has a horrible ticking and rattling sound at idle. It almost sounds like a big diesel truck. It only started a few days ago, before then it ran and sounded perfect. I added headers 500 miles ago. It seems to still run ok, I am not gettting on it though, but it sounds horrible at idle and slow speeds. My predator diagnostic shows these results at idle, please translate what they mean and if thet are good or not.
4.8 psi MAP
670 rpm(I know this one)
18.3 spark
109 IAT
.72 MAF
0 degrees knock
-7.81% long term
-.78% short term

Try foot-braking it in D/OD and listen to the sound. If
it gets louder with gas pedal then it's an exuast leak.
The Predator numbers don't look unusual to me. Though
that's a pretty low idle spark advance.
