put in new plugs, fuel trims off...help?!
ok i put in new plugs, i had a problem of running lean before and figured i might have messed up some plugs. well it fires a lot better now but here is the thing. before i would go out and the mV on the o2 read 870 and now they read about 900. the fuel trims were at about -1.56 or -.78 and now they went there once but then went right back to aobut -6 or so. will it just take time for the computer to adjust to the new plugs? should i just check again in about a week or so? just wanna make sure thats normal

Did you disconnect the battery. It might be re-learning.

I presume you are talking LTFT's. If it's STFT then the computer is simply relearning. If LTFT's are positive, then you are probably running lean, negative - rich, 0 - perfect.
Also [obviously] at WOT you only need to pay attention to WOT cell (#22).

If the ltrims changed on their own it would not effect WOT.
