I took my stang for its first road trip today after the cam and dyno tune. After going 60-65 on cruise control for about an hour I hit a light. When I tried to drive from the light, as soon as I would engage the clutch the engine would sputter. Did this twice in a row and on the third it worked just fine. Happened on the same trip at another light 30 minutes later.

On the return trip, no such problems. Also, on a cold start first thing in the morning my car will shoot up to 2k rpms and do a "hard idle" I guess I would call it. Could the two be related and is it most likely just the dyno needs a small adjustment?

 

I know there is a TSB for the fuel pump acting up after cruising on the highway.

 

Mine was running like crap kind of surging not sure if it was a result of the cams etc. I installed. anyway decided to replace the fuel filter with a high flow unit and havent had the issue since.

 

its the TSB for the fuel pump as you do have an 05 GT......it is not the tune!

The tune on mine for a cold start will do this...jump to about 2K rpms and slowly come down to 1100-1200 rpms for about 30 seconds and then go to my idle which is set at 850-900 rpms shortly after that....this is totally normal on a cold start!

 

Alright, glad I'm not alone on the LOUD startup in the mornings haha.

As for the TSB, how much would that run to fix and what is all involved?

*nvm found prices and labors per the TSB. Thanks

 

glad you answered it but if your in warranty they should cover everything.....

 

I've been out of warranty for a while now.
