[Spumato]

I will repeat myself again, I have just resurrected a vehicle that sat for 18 years. Sitting at any timeframe is death to the Porsche engine. Whether it be 60 days or 18 years. Time still is time still. And gas has increasingly become less stable than it was even 5 years ago and separates. Seals dry out, and things gum up. This is a slippery slope that cannot be stressed enough. I know that the OP is having issues, but let the rest of the forum take note... Porsche's are the best engineered motors known to man, and they yearn to be driven and driven hard at each pass. Run them often, drive them more. Bury the tachometer to the red line at each and every shift, and she will reward you back. I have learned this the hard way and wish the OP and all many happy miles of smiles!
