Had some questions for you guys. Recently when changing gears it seems the motor sputters, it's almost like it bounces before you feel the full acceleration from the next gear. This happens in any situation where I'm using more throttle then I would normally, or maybe past 5psi (if that makes sense). Other instances of the issue reoccurring would be anytime Im past 3,500rpm and am looking to jump on the throttle quick, it seems to struggle to get going, however, once it does clean up, everything seems fine.
Is this a Fuel system issue you think? Just wanted to get some of you guy's thoughts before I start checking it. After researching on other similar issues, so far I'm looking at
Check MAF sensor
Check Spark Plugs
Check Fuel Filter
Check all Turbo Connections
Dirty Injectors?
Any particular one you would recommend doing over another?
Thanks Guys.
