lol! Yes, I was planing to do that already after reading some posts of people saying that using shell gas helped in certain situations.

Thanks,

 

Yep my tech said the symptoms of air/fuel problems are hard to tell apart, but when the HPFP goes it will throw up a low pressure fault code that they can read off the system, whereas on the air side you don't get any faults unless it gets so bad that the computer detects incorrect engine operation.

 

...or you might just have the 2500-3000 RPM hesitation that many others have and Porsche has never found a fix for.

 

Hi, Thank you. I'm aware of the issue. My car does it all the time and its not subtle at all.

 

To be honest, Porsche has never found a fix because they refuse to acknowledge the problem.

 

The good news is, I think my car had a bit of the stumble before the new throttle was put in, and it seems to be fixed or at least lessoned now. So you might be killing two birds with one stone when you get a new throttle body fix your surge problem.

 

Hi all! thanks for all the help and feed back, I was able to use the information to request that the dealer checks the Throttle Body and they did found a bunch of dirt and gunk stuck around in there they cleaned and readapted the TB to the car and seem to be perfect now. I only had a chance to do a 30 minute drive along the airpot parkway in Ottawa to my house but idled smooth no hesitation.

again I want to explain that the hesitation i had was present at idle it's not related to the 3000k rpm or anything like that, It was hesitating all the time through out the rpm range.

hope this helps someone else. And again thanks!
