Hey I went to my local autozone and got these codes pulled after a 300 mile drive, the CEL jsut poped on.
17521 bank 1 sensor 1 resistance too high
01113 error occurs intermittant
16684 misfire reconized
16687 cyclinder 3 missfire detected
16686 cylinder 2 misfire dectected
16891 idle speed control system rpm desired valve
16689 cylinder 5 misfire dectected

can someone please tell me what it all means in dumb speak and what i am looking at to fix. all i can gatther from it is my o2 is bad and i think it was over reved, but i could be all wrong

 

So the CEL just went away after a fill up and a quick burst of speed on the high to pass a car. had autozone check it again, and now there are no codes, WTF is going on i am way lost, and i fucked or was it jsut a fluke. any help will be greatly appreciated. and now the damn thing has come back on after like 2 days of it being off, i guess i will check what the codes are this time, oh and also what does this button doin the picture below.

if you cant get on the web site it is the button just to the upper left of the shifter it is just a on off switch for something to what no idea please help!

 

16891 idle speed control system rpm desired valve

as you suspected its the ISC ( RPM higher than expected ) problem is the throttle control unit,

all the other codes are probably caused by this and the O2 sensor is only doing its job by detecting the misfire so I doubt its that,

appols for taking so long to answer ive been away for a few days

 

thanks! well that is what i figured it was so i changed it out and now i am still getting miss fire on the cyclinders so i figured i will just change out the plugs and see it that clears it up. thanks again
