Hi,

My 2003 Freelander TD4 sometimes seems to lack power. It seems to only happen when cold although not 100% sure about this. It is also only temporary and clears itself. I can still hear the turbo working when this occurs. It just feels quite unresponsive although if you really press the throttle down the car does accelerate. Just feels very sluggish and you have to give much more throttle input to achieve acceleration.

I have also noticed that sometimes when pulling away or accelerating from very low speed, there is a brief period (half a second) where the engine does not respond to the throttle input. Not sure if this is a separate issue as the 2 things don't seem to coincide always.

Any ideas please??

thanks

Rob
 
Hi,
just had my td4 serviced today and i had a similar problem, when start from cold a bit bubbly until rev up she clears straight away, but when ideling comes back, mechanic put in some diesel treatment he thinks it may be a stickey injector, suggests i put in some more treatment and see if that helps . dont know if your problem is the same , best of luck give it a try cant do any harm..........

Your second paragraph suggests a faulty MAF sensor Try a drive with it unplugged and if the flat spot has gone that will confirm it needs changing.
 
many thanks for the reply.

Not being very good mechanically, I will get some help with this. If it is a faulty sensor, do you think it will show up on a diagnostic test?
cheers

dont think a faulty maf will show up on a diagnostic test.but as chaser says it will if its unplugged and then taken for a drive.it worked for me.tim.
