1.6tdci focus pulsing on acceleration
Hi Guys,
Got a bit of an odd problem, sometimes when accelerating the car pulses or surges. This seems to happen after long periods at open throttle , such as going up a national speed limit 14% hill near my house.
I have also noticed a distant whirring noise that accompanies this and when the acceleration pulses away, a noise like a wastegate noise, not a whooshing one, but a light chirrup noise.
I cant work this out, so any bright ideas would be much appreciated!!
Thanks Rocky

Is it metallic sound .. bit like thin metal vibrating? .... i had strange sound when accelerating and have just found a split intercooler hose ... a guy in my local garage knew the noise instantly. Only happened when the car was under load.
