99 accord F23.....idle when stoppin issue and trans question?

[pacocrix]

99 LX accord 4dr F23......replaced wires and plugs (all ngk) about 10k ago (just maintance nothing really wrong)....got two symptoms that have slowly gotten worse

when driving everything is pretty much ok, but if u stop really quick the car trys to die/stall u can pop the gas and keep it goin. or if your are in park and rev it up high when it idles down it idles down too far and trys to stall.....? ive been getn randomly, a multi miss fire code CEL goes on and off for this all by its self......im thinking dizzy, or maybe fuel filter or O2 sensor....idk....also if u try and punch it the cars just sputters

trans question- 1st gear started slippin a while back after research i found out the this yr/mdle accord has a horrible trannys, so ive been keepin the fluid changed about every 6k and it really seems to keep the life in it, but its starting to slip in all gears.....this has got me thinking that maybe its not as internal as i was thinking (was thinking syncros in 1st were bad) and could just be the torque conv. since its now same symptom in every gear......but im not a tranny man so not sure on my logic here.......any help would be awesome.....ive got to change the axles soon so was thinking about throw'n in a torque conv. but if its justa waste of time then i wont....?


thanks
