merckx Posted September 27, 2008 Share Posted September 27, 2008 (edited) Can you est each one with a volt meter ? You can measure the resistance, the accepted values are in the manual but I don't think you'll get a conclusive answer as to whether they're faulty or not. They may well behave differently under load. I had a misfire and I bought some new coilpacks, they made no difference at all. Misfires are very difficult to diagnose. On my car I removed both the crank/camshaft speed sensors, give them a little clean as they weren't really dirty and refitted them and the misfire disappeared totally.
