misfire? part two

[TRDmod]

ok, remember last topic b out my car sounding like a wrx...well, when its warm and hot the wether i mean its sweet as, but at night bout 9pm and after, with out fail it will have the same symptoms, at first it was just sweet as, as soon as it gets warmed up, it stops, but now, it basically doesnt even after 10 mins of driving, tghen it still does after ages....then another thing, a light goes on, a red one, looks like a box iwth two tubes coming out of left and right side with three heat waves emanating from the top of this box, i thin its the engine light or catalytic converter light...it goes on after driving forawhile,t hen i put it on neutral and coast, and it disappears, hopes this gives more clues....

but yeah, it doesnt seem to subside as quickly as before..
took it to the shop and they said they have to hear it to diagnose, but everything they stgart it its perfect
!!
