2002 Renault Scenic Very sluggish in all gears

Hello. Thanks for the donation. Much appreciated

We will need a little more information before we can offer a diagnosis ! Is the engine management light showing? Is there no power at all time's or just pulling off. Does it feel like it's missing. This could be a clutch issue?

With no MIL on. We are shooting in the wind really. From your description I would be saying it's a clutch issue? But if you just had it replaced it SHOULD be OK. You could have the garage who repaired it check it for you ! It could also be a plug fault/plug lead/coil/coil pack. CKP (crankshaft position sensor) there are numerous sensors etc. . We could be just swapping parts for no reason. Have the clutch checked it should still be under warranty. Check you are getting a good blue spark on each plug. Which system of coil do you have (coil pack or coil on plug)? Check you are getting fuel to each cylinder. All these faults should be bringing on the engine management light?. But it could also be a fault on the cars computer?. Let me know waht you think and about the clutch?
