I have a '99 Toyota tecoma 2.7ltr The check end light came on. I went to Aamco to get the a diagnostic performed. The diagnostic came back Code TO303. Is that a cylinder issue or an ignition issue or other? Thank you

I get no information on a T0303 code, never heard of it actually, but there is a P0303 this is a misfire in #3 cylinder, could this be your problem?

Thank you mhpautos! My bad - - yes PO303. The truck just started "warming" up rough - feels like it's "missing".
