Did you take off the air box and hose from the throttle? I used a long extension and a tilting socket

I did remove those....having a tough time getting the wire off. My fat bear paws are getting stuck and I know a saws-all is not the answer.

Wow, that is a toughie. I remember I was able to squeeze my hand in between the exhaust manifold stem thing and the engine bay and pull the plug out. And I have above average size hands. My recommendation is to find small hands somewhere. Here's a picture that will hopefully get you a better look at what's there

what ever you do make sure its not cross threaded............



i made that mistake last time i changed my plugs, then spent a lot of money for them to tap the hole and put in a helicoil....all because I didn't think to make sure it wasn't cross threaded. Needless to say I'll never make that mistake again.

Get some long pliers to help pull the wire off if needed.
Then wobble adapter to get the plug out

Having the right tools helps a lot! I bought these spark plug sockets off of Matco tools that have a double swivel in them which work wonders and to get the plugs back in use a piece of vacuum hose and put it on the end end of the plug and use it start it so there's no crossed threads

Ill say this have the right tools you can do anything. I did mine takes small turns, patience, and know how. When I did mine the first time I broke the plug off in there. Took a whole to get it out. I bought a 270 piece tool set from sears a craftsman set and I'm constantly adding tools to it.
