Dear all,
Not a huge problem this, it certainly doesn't happen all the time, and it's mostly out of curiosity that I'm enquiring.
I find, occasionally, in 2nd and 3rd gears when accelerating slowly (such as when coming off a roundabout and getting back up to speed), that the 159 gives a little cough. It tends to happen at just over 2000 rpm. It's almost as if briefly the engine loses fuel or air supply.
It's a diesel, a 1.9 JTDm.
The EGR and throttle body have recently been removed and cleaned, as I thought this could have caused some of it. I have not had the EGR blanking plate / remap done.
Another thing that may valuable to know is that the acceleration profile in first gear (only) is not smooth. Up to around 3000rpm it is as smooth, but after this there is a giant kick up to 4000. I was thinking that perhaps the lumpy acceleration profile and the cough are related.
Has anyone else experienced anything similar, or have any ideas about what may be causing this?
All the best,
Andy
