Hello! I just bought an 05 porsche cayenne turbo and was going great for a hundred miles then is wasn't taking the gas normally. I pulled into a rest stop and when i came out, I started the vehicle and it would stay running fine for about five seconds then quit. I replaced the fuel pump and now it stays running but it runs rough if I accelerate. I checked the spark plugs and loks like they had been changed not too long ago with OE plugs and visualy inspected the coils. All the coils look like they were replaced and updated. I did'nt see any cracks on any of them. I'm about to change the oil with mobil 0W40 and see if theres any difference. I did have a code p2179 for a while.

 

You may have a clogged fuel filter. How many miles are on it?

Im sorry I hav'nt followed up on this. I forgot to plug one of the pump tubes in the fuel tank lol. The motor runs beautiful now.
