Can someone perhaps explain what difference the fuel pressure makes?
I would expect in a modern car with lambda sensor, if fuel pressure was too low the ECU would open the injectors for longer to still get the right amount of fuel in. What about if fuel pressure was too high?
I ask because I am at a loss with a soft and flabby throttle response on my 206 1.6 8v and now suspect the fuel pressure could do with checking. I recently drove a 1.4 8v of the same year which had the typical excellent Peugeot response and subjectively felt as if it went better than my 1.6! Likewise my girlfriend's 106 with its mere 1.1 has great get up and go. So I am disappointed to say the least. I've had it hooked up to a diagnostic computer and all values looked normal with no errors (have replaced crank position sensor and coil pack just recently which made no difference).
I have had good improvements adjusting fuel pressure on my old Merc 190E hence my asking, really.
