maybe the wastegate solenoid sticking.

 

laser ed - No need to shout chap!!

Have a search on here, have read something similar with regard to the fuel used. Seems Optimax can be the issue and so some people alternate between Optimax and BP Ulimate which seems to sure the problem.

 

THANKS WILL GIVE THAT A TRY

 

full throttle?

could be overboost.

I've also heard this is a symptom of possibly a failing MAF sensor.


PS turn off caps

 

yes full throtel, round about 5000rpm i get a kick and it backs of
where is the maf sensor.

 

How severe is the backing off? head against the windscreen job or just a mild loss of power?

The MAF is just after the Air box in the pipe work

 

From what i've experienced...

Overboost, was like someone switching off the engine, resulting in severe jerking (as said above)

Failed Maf. felt like the car was really hesitating/missing, but no real jerkiness.

Hope this helps.
May be best posting in Drivetrain or General Technical though.

 

its a mild loss for a few sec,then the power there agen but not full power.

 

Sounds like the MAF sensor.

thanks chris, i was told i could use carb cleaner to blast the dirt away, done that about 5 month ago when the idle was searching it was ok afterwards, the idle is still ok sitting at 800rpm but i will buy a new MAF and see how it is.

THANKS AGENE GENTLEMEN.

 

wastegate control valve would be my first port of call.

 

where do i find this
