Alright, driving to work today my 1999 TJ 4.0L lurched forward and threw code P0121. It's now slightly bucking, power is bogged down, and it gets significantly worse above 40mph. I put more oil into it, and drove it home to sit. Now I need some help on what steps to take.
I haven't done any recent engine work or electrical changes. However, I MAY have gotten water in the intake. I say may because I washed down the engine last night and washed out the K&N filter (I know
) and let it sit overnight. I forgot to check this morning, but it may be possible some droplets of water entered the engine
. From here, what steps should I take?
