On Tuesday last week, on my 2000 2.7 Boxster, driving down our street went over a very small bump in the road and the throttle went dead. Rolled the car back to the house and left it for 10 minutes, re-started it and the throttle was working again. When the throttle stops responding, the car just rests at idle.


Called the AA out, who found no fault codes. They followed me around the block where it almost made it back before going over a speed bump and the throttle went dead again. This time, it would not work with a restart, and would not work when left.

Had the car recovered to a local specialist (Williams Crawford in Saltash, Cornwall), who have tested another pedal unit, which did not make a difference. They've also checked the ECU as they said the plug was a little loose which would explain when the car went over a bump that the throttle cut out if a connector was loose relating to that function I guess, however securing the plug has made no difference, and beyond that they have not been able to find any fault.

Their next port of call is for them to try a new MAF and new brake pedal switch. If that's not the problem, they said it could be a wiring fault. 

The costs of the investigation work is growing, and I need the car back as I drive it daily. 

Has anyone come across this issue before? Any help appreciated. Thanks.
