Hello I just purchased a 2001 Boxster 3.2 the mileage is 90k plus I do not think it has had any service other than occasional oil change now and then in the past 5 years. The muffler has been removed to make it sound "cool" Yes it is getting a new exhaust system, But it will not idle. The car starts fine tries to idle then you hear a click similar to a relay and the car dies like it ran out of fuel. This all happens in about 5 or 10 seconds after starting I have recalibrated the idle circuit. And have not pulled any codes yet. I plan on replacing the fuel filter and spark plugs. Once you start the car and feather the throttle it is possible to keep it running and even drive the car seems as long as you keep it above 2500 rpm you can keep it running. Looking for suggestions on where to start.

Thanks
