smells like burning metal when downshifting
95 civic DX all stock
when i downshift it smells like burning metal, like gas is burning in the exhaust manifold. which i already had to replace because it got stuck to the old O2 sensor. (overheated maybe?) i changed out all the injectors and it idles fine now (was surging) but still has the smell.
checked the TPS, it reads 0.46-0.47 at closed and 4.6 at WOT. i read that its suposed to be 0.5 closed with a variance of 0.02. does this means its bad? needs to be adjusted or fine? the volts go up normally all the way, no weird jumps or dead spots.
i was getting an o2 code whenever i downshifted, so i changed it. now i have no codes and spark plugs look fine.
what could cause this?

It happens at 2000 rpm in 5th gear or any other speed, I don't think its the clutch. Yes, the exhaust has some leaks but it still shouldn't smell like burning metal should it? I don't have a cat.

the pan drips a lil bit every now and then, but i dont know why it would only smell when downshifting. i thought it was a bad injector but i changed em, so i have no idea.
and the clutch isnt slipping... not when cruzing at 35 in 5th gear, theres not enough torque to make it slip, plus i think i would notice, i have an ex cluster with tach.

i just wanna make sure you guys know that it does this even when almost no torque is on the clutch. i can cruise at 35 in 5th gear which it like 1.5K rpm and just take my foot off the gas and i smell it.

today i started noticing hesitation under acceleration, it feels almost like the spark timing is jumping around, so im gonna change out the ICM and see what happens.
