Just put it in and drive?
I have to fill up about 40 miles away, and they do have some down there.
I have done no maintenance since the Dragon since has been mine.
I am about to chance out the rotors, add SS break lines as well as an aftermarket high flow intake.

The previous owner had codes P0171 and P 0174, lean 02 condition. The delaership replaced the intake manifold gaskets under warranty in 2005. Had injection system service done at same time.

He replaced the ABS sensor & the ECM in December.
The air filter was replaced with a K&N in January.

That's the extent of any major repairs. Regular service at correct intervals, excluding the 6K

Best,
Your MAF sensor should only be cleaned with MAF cleaner.(should be available at NAPA, CRC is my fav)
It would be my guess that the MAF is the culprit in all of this.
I base that on the fact that you mentioned changing to a K&N filter.
Excess filter oil fouls the sensors in the MAF, causing false info to be sent to the ECU, which then throws a CEL.
