spongeBOB83 Member 3 Member For: 14y 2m 28d Posted 18/02/11 09:00 AM Share Posted 18/02/11 09:00 AM I have a customer who has an xr6 turbo and he says that when it gets to a certain speed it feels like a limiter kicks in but only really when he puts the pedal flat to the floor I have tried to clean and lube the boost solenoid but it hasn't seemed to make much difference is it possible a fuel pump not supplying enough fuel when the engine really needs it?

spongeBOB83 Member 3 Member For: 14y 2m 28d Posted 20/02/11 02:59 AM Author Share Posted 20/02/11 02:59 AM our customer said it fist started cutting out at about 120kph but now says arount 80-90 kph I don't think it would be the coils becuse the misfire would be there all the time it almost seems like some kind of governor cutting in could it be a faulty boost control valve?

Mr_4.0 Member 1,096 Member For: 14y 2m 19d Posted 21/02/11 09:18 AM Share Posted 21/02/11 09:18 AM Id try coils. Also check wiring loom for cam phasers. Link to comment Share on other sites More sharing options...
