91 XJ: idling problems
I've got a 91 XJ. When cold it has problems idling (whether in gear or not).
After about 15 minutes the idling problem disappears. Last time I checked
the plugs, the frontmost plug was in bad shape the electrode was nearly worn
away, I managed to gap it, but I really should've replaced it. Could this be
the problem?

Yep. That and carboning up #1, and helping to clog your cat.
Saving a plug could burn out your coil. Go get some Autolite plugs and pop
em in.
Could also be the throttle body idle air passage.

Re: 91 XJ: idling problems
I wish I knew how that one plug got so eroded while the rest looked great. I
guess I'll replace it tomorrow. Autolite's your recommendation then? The
other plugs looked great so I shouldn't have to replace them.

Re: 91 XJ: idling problems
How many miles are on the plugs? If more than 30K, I would dump them
all.
I also prefer Champion plugs, but that is just me.
