I have a EB 4 speed auto, the problem is that it seems to lack power on take off. The revs just don't seem to be there. And it loses power easily when going up a hill etc, but will be alright once its up to speed. Can anyone give me an idea on what could be the problem? Which sensor/ sensors would cause that? Could it be the transmission?

Hey Fox, welcome to the site!! Enjoy your stay!

Well, that sounds like it could be a number of problems.

Firstly, check all your plugs...they can often be the culprit. A good service may be in order! (Air filter, oil the works!)

Unlikely to be the gearbox.

One other thing which would do exactly as you say would be a blocked/calapsed catalytic converter. These will absolutely kill any type of performance. If its the original one its got a high chance it may be on its way out!

Hope some of my dribble helped anyway!

Plugs have been replaced, I've had a brand new cat put on about 4 months ago, air cleaner is fairly new, the oil has also been changed after I put the new head on it - And that is actually when the problem started. Nothing has been left off, and I'm pretty sure everything was put back and connected in its right place.

i had this when the headgasket was done on my car, switched a vachume line.

hows your fuel filter?

The fuel filter was replaced about 6 months ago as well. I think I also forgot to mention that the car does this only when warm...
