I was driving my truck earlier and it seemed like the engine started to studder. If i push it more on the throttle itll slowly work through, the turbo would spool, and it would slowly start to make the power it usually does. But driving under 2,000rpm where im just cruising it would seem like the motor is studdering and at slower speeds or going up a hill it would make the truck shake. I know its the motor itself because at idle it studders also. Please help asap thanks!
