150 D4D Hesitation / Surge

[shodown Senior Member Find all posts View Profile Close shodown]

Hi Guys,

Just recently, I have notice a very minor hesitation / surge while driving at speed. It generally gives the feel of two very quick hesitations / surges. They are so quick, I initially though it was a bump in the road...

I have checked injector feedback values previously which were ok:

Inj Cold = -1.1 / 1.0 / -0.4 / 0.1
Inj Hot = -0.2 / 0.3 / 0.1 / -0.7

Vol Cold = 10.37
Vol Hot = 6.32


Any ideas? AFM?

Cheers,
Kevin

There's a couple of threads on surging that might help. Have a read of this one first:

My apologies - I actually started reading that thread previously, but gave up thinking it was all about tthe auto box update.

Turns out, further in the thread a couple of people with manuals experienced similar and fixed with ECU updates.


Cheers,
Kevin
