Message	From reading the Other Thread, the Car will run on 6 if Pushed, and drop to 4 at Lightly Loaded Conditions.. that tells me a Posable lean Misfire on the TWO Cylinders at Idle/Part Load.. To me the plugs look like they are running lean, when they are running.. but not developing much Temperature to clean off the Black.. So they are not running very long when they run.. My Stab in the Dark Guess, is some sort of Intake leak/Injector Air leak ( Fuel Rail Mounting O Rings? ).. My Favorite trick for Checking that is to use some 'Brake Kleen' Spray Cleaner with the 'Snout Extension'.. Spray the Cleaner at the Base of the Injector while the Car is running ( CAUTION, SPLASHED IN THE EYES AND BURNS LIKE CRAZY.. so be careful... how do I know?? :) ) When you Squirt the Stuff around, and find the Air Leak, the Car will start to run better.. that is where your leak is.. As was mentioned, check all the connectors.. they can give all sorts of grief.. but I'd check out the Intake Area for posable leaks.. Cj
