As for the wrench size.. I bought the O2 socket. It'* great cause it has the cut out like a line wrench. If you don't want to bother with that, a crow'* foot looks like it'd work too.
It will...Did my first one that way.

Size? It'* a big crescent wrench. I have the socket, but I find the crescent wrench easier.

No luck guys, it didn't change anything, i am glad i changed the o2 though it was nasty....i will try the spark plugs next, if all else fails....who needs parts

i bought the socket and it was so easy with a couple of extensions, i couldn't find my pops 7/8" so i had to buy the socket......could any of my problems be caused by the MAF? Someone at the parts store told me to check the MAF, i got a spare one so, i guess ill just change it and pray it works.....maybe the gas pump, filter? im driving myself crazy with this thing and i am almost, almost, almost tempted to trade the p.o.*. in and get another car.....

was home for lunch today and decided to change both the maf and the coil just to try it out, so i change the maf and no luck, i went to change the coil and it has some sort of white stuff coming out from one busted end, so i try removing it and it wont budge, the plastic coating onthe inside had melted and was sticking the coil to the ecm, i changed the coil and disconnected the battery for about a half hour and no change, my next guess is the ecm itself, wires or bad plugs as i dont have the socket to remove the plugs and check them.....any further comment or suggestion is vey much appreciated.

That white stuff was corrosion. You should clean that down and add dielectric grease to keep it from coming back.

Did you swap all at the same time or seperately? And do you mean ECM or ICM? ECM being your car'* computer.
