Replacing Spark Plugs, 2003 Windstar

[elvisboy77]

Can anyone give me any hints or advice (other than take it to the dealer!) to replace the three rear spark plugs? The front three were of course easy to do and they were badly worn at 100k miles.

Thanks for any help!

I know on my 1998 I had to remove the entire plastic cowl that holds the wiper assembly. Once this big piece is removed you can easily feel each plug with your hands.

thanks to this forum, I pulled out two layers of plastic and the wipers and changed them out. They were in the 0.70 range ie worn out.

Your help is Much appreciated!

yup yup yup... My cowl is off right now (sealing the HVAC ductwork)...

Ive heard mixed opinions on spark plugs and engine break-in... Should I do the plugs? It's been about 5000 miles.

Check them and see if needed since you have had running issues. Check the Gap too.

They look ok, running a hair lean, but the plugs seem ok, should I get a brush and scrape off the dust? The van is off to get the O2 sensors changed tomorrow. Then it's off to the bodyshop.

Yeah clean the plugs off real good and then put them back in.
