Hello All,
I recently purchased a 1999 Porsche Boxster with 83K miles on it. It ran fine at first and seems to run fine intermittently. The car now has a pretty extreme hesitation and stall that will usually start after WOT. I just had it completely checked out by an experienced Porsche mechanic but of course it was behaving fine that day. It is not sending any engine codes. He smoke tested the engine and looked for any stored codes but found nothing. At first we assumed that maybe I had just gotten some old gas as not many stations are moving the high octane these days. I replaced the spark plugs today and changed the oil. The ignition coils appear to be in great shape and are not the original but Beru brand. To me the issue feels like some severe misfiring or fuel supply issue. Any ideas on things I should check next that would not throw a code?
