GT JTD intermittently looses power
Can any mechanics offer advise?
Just recently my JTD has been loosing power.
It starts perfectly every time, but randomly (and getting more frequent) it has no revs for a while. When this happens it takes anything from 1 or 2 seconds up to 30 or more sometimes with the accelerator down before the car picks up revs & power and works normally.
Also sometimes when driving in 3rd upwards, when accelerating, it is slow to pick up, then when the reves get to around 2k rpm the counter shoots up to about 3k rpm for a second or so, then drops back down and carries on as normal. Sounds and feels like the clutch slipping, but it takes a while to pick up before it does this, and only happens in higher gears - never yet in 1st or 2nd.
The car smokes more than I'd expect too.
I've read some stuff on here which sounds similar - seems to point towards problems with the turbo?
It's currently in the garage for diagnosis but they claim they can't find any faults, which is complete rubbish. I get the fault pretty much every time I drive the car now.
The garage are currently thinking it is a fault with the injectors - which incidentally have been replaced once already under warranty. They want to send them off to be tested and of course I'll be charged if they come back as OK.
It's an 05 plate, 71,000 miles.
Anyone got any other ideas?
