my 96 blazer with a 4.3 has one spark plug on the driver side that sits behind the steering stick. i changed all the rest just fine but cant figure out how to get that one out. anyone have any suggestions. thanks for your help.

 

I just did mine about an hour ago. The easiest way I've found to do it was to use a spark plug socket and a 3/4' wrench to turn it. I still need to pick up a set of wobble extensions- that would probably be the easiest way. Other ways as found on here..

Make sure to check for the proper gap- one of mine was off out of the box- the rest were right. And DEFINATELY use AC Delco plugs!

 

i used bosch platinum plugs and thanks for the info

 

Just undo the steering shaft? I found that to be the easiest... One bolt on the end, and it just slides off the steering box. It's keyed too, so u really can't muck up reinstallation...

 

the easiest way i found was a spak plug socket with the wobble built in to it.it makes it alot easier to put the new one in also.if you put a wobble on the end of your socket it makes it a little to long.
