So today on my way home from college i noticed a differnet kind of noise emerged from the depths of my 22re. Most of you have prolly seen my youtube video of my toyota at idle. If not search on youtube "22re idle" mines the first one. anyway everyother valve chatter is still there but a noise only under accleration its kinda like a sprin like chatter not valve but somethin else....

Thats a little vague

try to determine where abouts on the engine its coming from. Maybe get another sound clip if you can.

Yea i'm gonna video it tomarrow but its like a more noticeable and louder tapping/springy/pingy sound. And really only happens under acceleration.

Pingy? Change gas recently? Same octane?

oh a pingy sound?...you might have spark knock or preignition or whatever you want to call it. try running a higher grade fuel. Try using an engine cleaner (SeaFoam, or what have you) if you haven't already.
New plugs, wires, rotor and cap if you haven't already. Make sure they are the right heat range and gapped correctly.

If everything else fails...

check the ujoints

From experience...for the longest time it just squeaked/ticked/made dying squirrel noises...couldnt figure out what the grading metal noise was...turned out the ujoint was completely dry and actually grooved the race of the bearing...probably not this, but just a suggestion.

It only happens under increased Rpms even when sitting. It has an full entire new tune-up and i recently seafoamed it 2 weeks ago. Gas i'm about to fill it up tomarrow it has some lil old gas in it thats been it for like a few weeks.
