...P0357 means cylinder 7, P0358 means cylinder 8, etc...right?

Yes, Coil(x) Primary/Secondary Circuit Malfunction.

Cool. Thanks!

Got all the coils changed out today and it does run smoother. Still not as smooth as I feel it should be, though. I'm not very familiar with these cars, though...maybe it's normal. I don't know.

Going to check the codes and all that again after resetting them and letting it run for a while. Hopefully it's good to go! That way I can get get on with fixing the other codes...lol

My V6 is pretty smooth with the new coil pack. I got an Accel SuperCoil for $65.00
on eBay, and noticed the difference right away. Tuned it, and with 93 Octane, runs real nice.
Probably needs spark plugs, so will change them as soon as I can.

Got ya. Maybe I'll do those next. The car definitely feels better...runs better, too...just not quite like I think it should.

I was expecting to spend 50-60 bucks per coil but came across these and decided to give them a shot. They have great reviews and at that price, it's worth a shot!

Motor mounts/trans mounts ever go bad on these things?

For that kind of money you can buy OEM, (MotorCraft) which by the way is better than any thing you can buy, Accel, MSD, and yes mounts do go bad especially when you are talking about a 15 to 20 year old car

if you are wondering about the almost random burble and shake at idle, its an inherent mod motor thing. Some vehicles feel it worse than others. Can assure you from my experience its pretty normal. That is assuming you did take care of all the misfires

Ok, cool. Replacing the coils made it feel a lot better. I'll run the codes again this weekend to make sure the codes are gone, too.
