My 99 Boxster runs badly whenever it feels like it. I can be going down the road at 60 and give it some throttle, it rolls over like it's not getting any fuel. It runs like that for a while and the next time I start it, runs great. Then after sitting for a few days, it acts up on start-up. Dealer can't find the problem because it comes and goes when it wants to. 60000 mile service done a couple thousand miles ago (at 57000 mi.) now at 60,200. Car always ran great until this started happening. NO CHECK ENGINE LIGHT. NO CODES.
Anyone have an idea where I can look.
