Hi

Having problems with this vehicle going into limp home mode. seems ok if its driven just touching the accelerator lightly,but as soon as you put your foot down it goes into limp mode.it comes up with several codes the most frequent being p0121 throttle pedal/position sensor/switch A circuit range/performance, p1160 inlet manifold flow coherence, p1161 throttle position captor check coherence and p0170 fuel injection.has had new pedal and motorized throttle valve, have also checked wiring from pedal to ecu and throttle valve to ecu, all ok.beginning to wonder if there is a problem with the inlet manifold, there seems to be some sort of valve in the side, i can see a plate which is holding in a large spring.would appreciate any help

Cheers

Dave
