I have a top end problem near my rear sparkplug wire the one at the back of the engine not front of the car. i can take off the sparkplug wire as it is running. It does not make any difference with it plugged up or not . same idle sound. and the same thing if i unplug the fuel injector same idle plugged up or unplugged. Plus, i have a ticking/pinging or some would might say a pecking sound right around that area.I know that the rear injector is getting power as i have checked it. So little knowledge of the Porsche which is two week worth is that it could be: 1.Fuel injector 2.Sparkplug 3.Bad valve 4.bent spring or 5.broken valve. p.s the sound comes and goes pretty loud at somepoints Please i need help you may call if you want to 606-524-2287 Josh

could be a collapsed lifter not pumped up so your just drowning the plug...what does the plug look like? Are you getting spark through that wire? Could be a bad wire...also could be a bent valve in which case whats your belt look like?
