I am experiencing a chugging sensation when accelerating. It feels like the power is cutting out or I am getting short boosts of power. It happens mostly in 3rd gear but also happens in 2nd and 5th. I have a 06 MCS with CAI, Invidia Exhaust, and m7 Pulley. What could this be. I am at about 45,000 miles. I have some brisk plugs I am waiting to install. Would those fix my problems??

 

Do you have a boost guage ?

Wonder if your BPV is functioning properly?

 

No I dont. Any other way I could check that?

 

IMO I doubt the plugs are the issue......(you did go one step cooler when you did the pulley right?) If you pull them (the plugs) and swap them, be sure to look at the color......
A few questions......is the power cutting out entirely? Does it feel like the car is coasting?? Or is it just less power....like a hesitation? Any lights on? Any noises? What are you using for gas...? 91+ right!.
The BPV is possible, spring might be broken or something....sounds like we need one of the "real" pro's to chime in! Any more info you have the better and help future readers, and speed things up.

 

I havent changed the plugs to one step colder yet. It is not a cutting out of the power entirely. It is like a rhythmic hesitation of power. There are no lights coming on at all. Yes I am running Chevron 91 right now. How do I check the BPV? Where is it??

 

Like a YO-YO...have you checked out the numerous threads to see if the descriptions are similar?
