Can anyone post the DTC's from 1280 to 1290? I have either a 1285 or 1289, can't remember which and the dumbass that I am...went and cleared it before I wrote it down... this code has poped up before so it won't be long before it show's up again, but if I remember correctly it has something to do with the airflow metering... I have a nother throttle body with all the stuff on it and if I can swap the bad part out before this weekend, I'd be very happy. Heading up to the Lake Shasta area and would really like it running right before I leave.

it is a 2000 4x4, engine is a 360 and I have the K&N FIPK2 and gibson headers on it, no other mods at this point.

Can anyone help with this?

TIA
