2008 sprinter 2500, every time i start to drive I have no power for about 5 to 8 seconds nothing happening then slowly it starts to rev up engine and start to drive then its fine , there r no codes


Check the engine in neutral/park and depress gas and confirm engine is slow to rev up. If the engine revs in gear and little or no movement have the transmission checked.

this car is likely a drive by wire.(no cable between gas pedal and throttle actuator motor) Some one needs to observe the throttle to see if it advances when the gas is depressed.

The simplest analysis would be the connection to the engine computer with not a simple scan tool but a Chrysler proprietary analyzer to see the interaction of throttle position and engine RPM

Hope this helps?

My mazda drifter 2.5 D don't rev over 3000 rpm and don't go over 120 km when its in 5th gear,its like limiting.What can it be it never did it?


When you rev the engine and does not go over 3000 rpm is this in neutral or when driving in gear? Some vehicles have a rev limiter to not allow rpm over certain point when in neutral gear but is typically not limited when driving vehicle. This sounds like a very low rev limit but not abnormal if you can get engine to rev higher when driving. You call a drifter so truck must be non US market. Is this engine a 2.5 liter diesel 4 cylinder motor. Might just be your top rev and speed if this is the case.

Try to rev the engine while at neutral if you get the same vibration to pinpoint if its from the engine or the drive shafts. If the issue occurs at a certain rev it may likely be the variable valve unit. Check if possible if you can get errors from the computer.
