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
Forgot to mention that at times when the engine is started it continually surges from 800-2000rpm and does'nt respond to the acc pedal at all until its been switched off and on two or three times.
Check for coolant in the ecu multiplugs, failure of the coolant sensors allows coolant to be pumped up into the ecu causing a lot of throttle body faults, new ecu and sensor required and loom repair. common fault on the RFJ apparently.
Thanks very much for your reply Chris,nice to know there's someone out there! Had already found this info elsewhere on the net just before your reply and sent the ecu to Actronics on the 27th. They have comfirmed that the unit is contaminated and unrepairable. New ecu over £700 with vat! Expensive game this motoring!
