any help would be appreciated . Just replaced ALL COIL PACKS and PLUGS, still, after driving fast on freeway or accelerating hard, it starts to run rough and sometimes stalls at a light.
Hard starting and rpm fluctuations. Replaced battery, no change, replaced fuel filter, no change. Assuming it is the fuel pump after reading all the posts.
Car starts but soon stalls out. Took it in to the Porsche dealership. Said it was a the fuel pump. I have owned many cars in my life and never had a fuel pump issue. Would think a Porsche would have a better pump. $1300 in repair cost. Amazing
5/16/15: won't start, got AAA service, jumped, drove home ok. 5/20/15: started, died in seconds, towed to dealer, replaced fuel pumps. 5/22/15: four wheel problem yellow light showed up, called the dealer, told me it's ok, it happened to them often. Might need battery replacement soon. 5/23/15: "four wheel drive system failure" message showed up when started, along with that yellow four wheel signal. Drove to buy something, won't start when coming back. AAA jumped and got home ok. Now afraid to drive it out. Any suggestions? Thank you! Cindy
