At cold start or 25mph 2nd gear cruise the car does a ton of sputtering. Plus hard through redline just wondering where to start? It happens cold or warm here is my phonetic noise...

Wow Im funny. I should of done it in caps no mufflers.

 

Wow 2k.......do a search for 3k hesitation and never even try and boost the car cold. Grounds are the most common fix but not a garuntee. The only 100% fix has been the PFC swap.

like they said, you should warm your car up COMPLETELY before boosting!

 

This sputter isnt in boost nor would I boost/rev a cold engine. This is at cold idle warm up or just driving at 25-30 mph in 2nd gear. No boost no acceleration just maintaining speed. I have the PFC and have switch between gas brands but still running 93+. Grounds huh? Which ones?

 

If your running a PFC and have this condition I would suspect a tuning issue....there is a forum just for the PFC and other third party ECU's.

 

Cool thanks for pointing me in a direction before I start spending money.
