My 04 V6 is eating me alive

First water pump...then drive shaft...now the **** thing has a fuel system problem that causes it to drop RPM and eventually stall out after 30- 40 secs. Starts up great and purrs. Then starts to cough and hiccup and eventually has seizure before dying out. All this at 57000 mi, bare_ss naked(no warranty) and within the last 30 days! In the shop now. ECM? Waiting to hear if it should just be shot and put out of its misery...if it was a horse...

Find someone with a diagnostic tool like the Durametric software, a PST2 or PIWIS tester and have the car scanned for faults.

Report those faults back here... then we can give advice.

Get rid of it before it destroys you. Fix it and trade it in on a newer one with a warranty. It wont stop. Cut your losses now. Now is a great time to make deals on cars. Take it from me...I had one that I had to shoot in the head.. :angry:

Relax... doesn't sound like the end of the world. Wait until the codes are accessed so we can narrow done what system is at fault.

PIWIS showed NO faults...I stood right there while he ran the diagnostics with engine jerking, yipping, kicking --trying to get one more heart-beat...before finally straight-lining. Other techs working on other cars were looking over their shoulders probably wondering what the hell I could've done to make such a cool car like this slowly choke dead like an abused dog on a chicken bone. How can a problem such as engine stall from fuel cut off not result in a code? :cursing: I DUNNO

Turns out fuel filter had blockage which in turn caused fuel pumps to dive over time? Mechanic says we need to replace both pumps. He replaced filter and said pressure was still low. $1,100. Pumps on order. Will get it back in a couple days. Oh...now I'm also getting the neck-jerking down shift joy from 5th to 4th (or 3rd)...which evidently is indicative of the valve body needing replaced. Soooo, if I want a ride that is smooth-shifting like most vehicles(including Fords, Chryslers, Hyundai, Yugo, my old '75 Vega) I'm going to have to shell out big dough. ;) My first experience with a Porsche has soured, boys. I have looked at the bright side and thanked God for giving me the insight to NOT buy a Cayenne w/ turbo, TPMS, air susp. , seat and steering wheel heaters or any of those frilly things that really would be busting my chops now :rolleyes:

Some cars are just lemons. Sounds like you have one. Not all Porsches have this many problems. Like I said...Fix it and get rid of it. Get a newer one with a warranty.. Then you will be a happy Porsche owner again like me :D

My wifes 04 CS has gone through 3 fuel pumps! 2 on the left and one on the right. Tranny valve body bad, plastic cooling pipes bad, spark plug coils bad. These are just a few of the failures we have had. If it were not for a aftermarket warrenty we would be broke with a broken car! I tell everyone I know "Don't buy a 04 or 03 Cayenne!" Now whenever my wife tells me the car is broke or she is stranded on the side of the road I don't get my blood pressure up any more. I just say "ok, here we go again." I hope this is the last of your troubles but I would expect more problems in the future.
