Yeah, pulling codes is easy you'll just have to look then up and sometimes it just gives you an area of things to check. Sounds like water got in the coil packs for the plugs...

Try plugs and wires first. Coil packs are $80 and are probably unnecessary. I had the same issue (code was a misfire in one of the cylinders) and just did the plugs and wires. Fixed it completely.

Use some dielectric grease on the plug wire to plug connections and you'll never have to worry about this again.

You likely don't need to replace anything (unless your plugs and wires are due to be changed anyways). Unplug your spark plug wires, and check for water around the plugs. It happened to me. I had less than 1/8" of water down around one of the plugs on the driver's side, and that was enough to cause it to mis-fire. I got rid of the water using a piece of paper towel to soak it up, then I blew it dry with compressed air, added di-electric grease in all the spark plug boots, and re-installed them. Don't forget to clear the codes, then fire it up.

So i pulled out all the plug coils and there was water on all of them. So i dryed them off and stuck a paper towel down there to the plugs to get anything that was still there. it ran a little better, but still very rough between the 1500-2k rpm range. any other suggestions. My parents are just saying go take it in (its thier car).

There's probably still water in there, keep some paper towels in there and let them absorb the water for awhile. I did the same thing to my old car and after getting all the water out everything returned to normal.

This happened to me when the detailer blasted the motor w/ disregard. The truck ran horrible and displayed symptoms you described. When we pulled the plugs, it was all gunked up. Changed out the plugs (that I bought from the dealer) and all was well.

So went and got some NGKs from kragen today thinking spark plugs were spark plugs, i guess not. I guess im going to have to go to Toyota tomorrow and grab some dual ground plugs. .044 spacing correct?

What was the CEL code? (maybe I skipped over it - but it sounds like you went to coils/wires based on feedback not on the CEL data)

.044 is the correct spacing, but you WILL have to regap them.

x2 on the CEL code.

Might try cleaning the MAF. The CEL codes would be a big help.
