Autozone has motorcraft but you have to order them, they don't carry them in stock. They do have MSD and ones called Duralast which have a limited lifetime warranty. The Duralast are only 30 bucks for the set, MSD are 87? I can't find a store here that sells Taylor or Motorcraft in stock. I know I can wait, but would really like to do this today so I can see if all is well and cancel my appt. for the diagnostic at the garage on Wed.

I've run duralast wires before....like anything else, they worked. The choice is yours, you can't go wrong with 'lifetime warranty'. If you have a problem or issue with them, take'm back and get a new set. I did this every year faithfully with my taurus.

Just went and bought wires from NAPA and put them on myself. Took the car for a drive and it's running a lot smoother but I did get one tiny chug when i hit 40mph. Nothing like it was doing before and only happened once so far. I'm going to take a ride on the highway and see what happens. The check engine light is off because the battery was disconnected to clean the posts. Do I have to drive it around for awhile for the computer to reset and if it keeps chugging, should I follow through with the diagnostic test tomorrow?

Re-learn takes...say 10 miles give or take. If nothing else, you might have to take the ignition coils off and bring them in to autozone to have them tested.....I know all of the a-zones here have testing equipment.

just got home, still chugging bad when i hit 40mph....where is the ignition coil? I'm just gonna take it to the garage tomorrow and have them run a diagnostic on it. My nerves are shattered. I probably just about drove 10 miles after putting the new wires on...maybe i need to drive it farther?

The coil unit is mounted just off the cylinder head, remember when you changed out the old plug wires.....next to the air filter box. Its helded down by 4 #25 torq bit screws, and a 3-wire harness plug connector has to be removed. But, in this case, you might be better off with a diagnostic run to play it safe. Almost sounds like insuffient fuel...this is where a fuel pressure test gauge comes into play along with a scanner paying close attention to fuel trim data.

Yeah, I decided to just take it in tomorrow morning. It needed new wires anyway so now their on and I'm sure I paid less for them than the garage would have charged me, plus labor. I hope it's not a bad fuel pump...can't afford to fix it right now if it is. Just really blows my mind that the old man I bought it from had no problems at all until the guy who was there before me test drove it and said it hesitated a lot. Still think he did something to make it run like crap trying to buy it cheaper. Tomorrows test should tell.

Well, look at it this way Cindy, if it turns out to be more than you want to deal with, you can always take the old man up on his offer.

Cindy,

Don't assume the new wires are good - test them the same way you tested the old ones - it won't be the first time a new part was bad out of the box. And don't be surprised with multiple things wrong in a car. Old plug wires often go bad and any shop would have almost automatically changed them in this scenario.

Did you check all of the connectors on the coil pack when you plugged in the wires? maybe one was corroded? Did you shine a light down the plug hole and make sure there wasn't water pooled around the plug?

Did you check that the plug wires were plugged into the correct posts on the coil pack? In a waste spark setup I think it's possible to swap plug wires on the paired cylinders and the engine will still run, but the computer will get confused. (I am just guessing I never tried it)

If it's a Zetec then keep it - it's worth fixing!

I have to say this - I never heard of someone selling a used car through the newspaper who allowed a stranger to do a test drive alone. I suppose it happens but I wouldn't be surprised if the guy who sold it to you was selling it because of the cylinder miss.

When I bought my most recent Focus, it had the check engine light on. If it had a cylinder miss I still would have bought it. There's a lot of people out there like me who look specifically for used cars that have easily fixable problems when they are shopping for used cars. But there's not nearly as many people like me who do this as there are people in the market for used cars that just want everything to work out of the box.

After I bought my Focus, after dropping $500 into a set of new tires, replacement rims, and a pair of O2 sensors, I could have turned around and sold it for close to $1000 higher than I paid for it. $500 for a weekend's hobby work isn't a bad deal. (I didn't sell it)

If wires don't completely cure it then go for coil next. My last go round, the wires cured about 70% of the missing, the coil took care of the rest. A coil forced to fire harder by bad wire can sometimes partially break down inside.
