Acceleration flat spot
Hi all,I have just joined this forum,I was Hoping some of your members may point me in the right direction.my car is a peugeot 307,2003 model with the 8 valve 1.4 petrol engine,the problem is I am experiencing a hesitancy/flat spot. when accelerating, I have changed plugs and air filter,there are no stored codes after scanning,I have previously changed both water temperature sensors for cold starting/running,I cannot find any air leaks,was thinking of changing coil packs,Maybe beginning to break. down?what does anyone think?by other suggestions? Cheers,great forum by the way!
Re: Acceleration flat spot
Try disconnecting the MAF sensor (if it has one!)
Certainly on the 2.0 HDi, if you do this, the ECU has default fuelling maps - so if it runs better, the MAF is suspect

I don't think he has one. This will use a MAP sensor.
