I don't mean to be a jerk, but did you look at the codes?

There are 4 misfire codes and 1 injector connector codes. It's not that bad... I just need opinions on where to start.

You already got a reply on the other forum

Start with a inspection of the cats - since this is the potentially most expensive failure. Have the front cats checked with both a rubber mallet and with a IR thermometer - exit temps on each side should be much higher than entry temps to show cats are functioning.

If the front cats have broken down then that debris can also be blocking the rear cat screens. Rear's normally can be cleaned and recovered, failed front will have to be replaced.

You start from there, then move to the MAF and if MAF requires replacement recommend ONLY genuine Borsch MAF currently around $180.

Do a fuel system cleanup with Stabil Blue ($8 bottle is two applications) and get a new fuel filter (Bosch is $35 online)
