Lack of acceleration.

[stanny2k]

Hi all,

New to the forums & I've just purchased a 53 plate Mazda 6 TS2 Diesel.

First of all, this is my first diesel, so I'm getting used to moving through the gears differently from a petrol car.

One thing I have noticed on my Mazda is that, for example: when I come around a round about (in 2nd gear) and enter an immediate hill, the car struggles like mad to get up the hill. I'm not talking a really steep hill or anything, the hill is quite small to be honest, about 60m's long & suppose it gradually raises approx. the height of half a house (if that makes sense)... Is this normal? As I said I'm only used to driving petrol cars (ford fiesta 2001) & I had no problem climbing any hill in 2nd gear, even 3rd gear sometimes...

Not sure if this is related in any way, but when I change into 2nd gear (from 1st) at anything over 2000 rev's the car kinda shunts as if I'm taking my foot off the clutch too quick, or accelerating when foot still on the clutch...

Few minor problems I'm experiencing at the moment. Hope someone can help.

Many thanks.

Ryan

May be there will problem with Fuel filters amd spark plugs..Just check it..Or just it needs a good service.Some times this problems occurs due to transmission or clutch issue..

I know it's an old thread and I don't know if you have found any answers yet.

I used to have a diesel 4WD years ago and learned that driving a diesel is different to a petrol car.

The main point with diesels is once they lose momentum they do not recover very well and on a steep hill may find yourself shifting down into even lower gears very quickly.

When approaching a hill for instance, you need to change down the gears and build up the revs before you hit the hill (or corner) and the engine will hold the momentum much better. Diesel engines have little power or torque once they lose their revs below a certain range, whereas petrol engines have more flexibility here.

Watch how truck drivers do it, they have learned to work with the diesel's characteristics.

All this is assuming you have nothing creating any problems with your engine.

You may have been told that diesels don't have spark plugs and distributors and require little maintenance. Fact is they do require regular maintenance especially oil changes as they get high carbon buildups in it.

Another myth is the never need to check the timing belief, not having a distributor. Fact is, many diesels do drift off their timing settings at times which affects power output. It's a simple job, but best left to the pro.
