the has stayed on and if know the codes i have multiple cylinder mysfire and cylinder misfire, and i already replaced the ing coils and kn air system, plugs and wiers and spark plugs, and even took it in.

I am out of ideas.

any body know anything i don't
Thanks.

 

Try posting what vehicle/engine and the CEL code you got. Also the CEL will not go away just by replacing the worn parts. It needs reset.

 

my bad im new at the sight.
it is a 97 tacoma 2.7L (cod 3000) and reset it once but it came back again

 

go get the codes pulled again and have them reset it right afterwords, post the codes you get from your new scan up and we will try to point you in the right direction
