Hey guys new to the forums and xr6t scene.

Got a bf xr6t which the last week has been cutting out/stuttering under load when wanting to pick up the revs.

Today engine light came on and has stayed on. Had a mech check the fault code and it came up as Wastegate.

Is the wastegate damaged or getting stuck or bov? Wud that be causing the cut off and stutter? Or is that the ecu throwing in to limp mode.

P.s the last week I have been hearing the flutter noise on de excelleration where as before could not hear it.

Car is stock apart from catback exhaust.

Anyhelp appreciated guys.

Cheers

Sounds like you might have a puntcure in your actuator diaphragm causing the car to overboost which pushes the car into limp mode.

The symptoms you notice, is that the car goes harder on initial accelration until you trip the over boost setting which I think is around 9psi, and then its limp mode...

I would be considering changing your actuator to fix the problem.

In the mean time to try and stem the overboost, appart from driving the car more gently, you could also loosen the clamps on the rubber hose that connects to the throttle body, this should keep your boost just under the threshold...(this has worked for me in the passed...not saying it will work for you)

Is it actually over boosting ie measured oneva quality gauge.

The pcm will flag wastegate failure whenever boost pressure is not in line with what the pcm is commanding.

Wastegate failire could can be boost high or low and will usually have a couple of other codes present that allow diagnosis. Ir boost pressure sensor high/low.

You neen to give the car a good mechanical checkover and physically messure the boost before working out a course of action.

Ok thanks guys I will give those ideas a go.

On the boost gauge it hits about 5psi and by the time I hit 4500rpm that's when it cuts out and wont let me push it anymore.

When did it last get a set of coils?

I recon Ralphs on the money.

Coils im not sure wen they were last changed hopefully can get it in at a mech later this arvo. I will have a look at the coils though thnx ralph

Check the plugs and gap at the same time

Yeah that's not a boost spike issue...it does sound like coils
