YO! failed the smog test today . in the words of the mechanic dude.
" The RPM's start dropping when the throttle is held straight. there might a be a possible surge or misfire "

SOAB! cant believe my car didn't pass :/ the check engine light is off too! So misfire i thought id check the plugs

i replaced dist cap and rotor. so that's checked of the list.

this is what my 4 plugs looked like in LEFT ro RIGHT order - 1234 -->

Anybody got any clues as to what may be causing the car to drop rpm's when its held say at 3k... itl start going 2.9 then 2.8 . its not a HUGE drop but i did notice that after the dude told me about it. also when i let go off the gas at the bottom of the rpms i head a misfire. :/

HELP

got 2 free re tests in 30 days. so id like to get it done asap
