Hello All,

I was recently changing the spark plugs on my 1993 tempo and ran into a problem. The #3 plug (from the left) is stuck and cannot be opened. I replaced the other 3 and took it to a garage to remove the stuck plug, but the garage could not open it either. As a result, the car is starting to hesitate a bit while accelerating. Has anyone encountered this problem, or can anyone provide any ideas as to what can be done to remove the plug?

Clean the area around the spark. Spray a little bit WD-40 around the spread of the spark. (Not too much). Wait a while. Use a long socket wrench that gives you more torque. If you don't have it, buy one somewhere. I think you can remove it anyway. When you put a new one, be sure not to make it too tight.

your main problem is to ensure that the block is COLD, but the only way to get the bugger out is to break its grip

WD40 may do the trick, its going to be expensive if you carnt remove it

aye make sure the block is cold. soak that thing down with some good old wd40 as Minge says. Then go in with the socket and a breakerbar. if you dont have one and have access to a narrow diameter pipe that is over 2 foot long you can possibly use that. socket and wrench over the plug as you would if you were trying to remove it with just that. Then slide the pipe over top of the wrench handle. use that bar to get extra prying strength.

Yes use penetrating oil / diesel fuel / tranny fluid ... let it soak a long time (hours) .... then get out an air impact wrench ... set it to low in reverse and let it hammer away ( 5 or 6 mins ) then increase the pressure and repeat ...

never use champion plugs in an alum head ( steel on alum just welds together ) unless you pull them every 6 months ........ use a coated plug ( NGK , Autolite , DELCO ....bosch )
