[QUOTE="CHOP SHOP, post: 1554410, member: 17493"] I am fighting a 4runner right now. It eats one spark plug regularly. Some background...... The rig ran awesome and had great power. Always left a black smoke/soot ring on the ground when fired up cold. Started to develop a "miss". Found out it had a bad injector. Put a used injector in and it was bad too. Went to DrInjector and got some new ones. Put all four in. Truck runs good now. Fast forward a month and it get another "miss". Check the exhaust and find the cold hole, pull the plug and its nasty and cruddy and black. Put new plug in, GREAT!! But it gets hungry and eats about a plug a month. It has great compression. The valves are set correctly. Im stumped? Why does it have to be so hungry? Im tired of feeding it plugs. Could this thing have run lean with the bad injector and burned a valve seat thats not showing up on the compression gauge? [/QUOTE]
