here are the codes I got from autozone

P0303
P0171
P0300
P0306
P0305

I put a multimeter to the 1 and 3 spark wires and got 10.8 on one 10 on the other they are about 2 ft cables, I assumed this means they are okay.

I rented a fuel pressure gauge from auto-zone and have no idea how to hook it up now.

anyways here's details on when/how my engine started acting up

hauled a trailer some 1000+ miles and towards the end of my move it started accelerating slowly. 6-7 months later it progressively gets worse and just now it started misfiring on a lot of cylinders

I really want to fix this myself because I can't hardly afford the mechanics...in a pretty tight spot financially, but I've got around $800 i can throw at the problem. am i better off sending this one to a mechanic?

Hmm, seems like you are running lean for some reason and that is causing misfires.

Pulls a few spark plugs and see what they look like, replace them no matter what as well.

Checking the fuel pressure is another good idea, although not real easy either, i don't think we have a check port.

I would do a FULL tune up, it will help one way or the other.

Change the spark plugs, plug wires, fuel filter, air filter, clean the MAF with MAF cleaner, change the oil (not needed but a good idea while you are doing everything else), run some seafoam though the system, then clear all the codes from the ECU.

After that, unplug the battery for an hour or so to reset it and see what happens.
