Ok. Cheers.I'll look into it.
It had the cambelt changed and also the uppipe changed to decat one.
I only drove back from garage about a month ago but because the turbo was knackered it's taken me until tonight to get it started again as I completely decatted it as well.
I did notice that it was rocking on idle when I drove back from garage.
my mechanic might have loosened engine mount to get uppipe out?
I'm gonna have to call him.
I once had the engine mount nuts missing on one of my old scoobs! I went around a right hand corner very hard and there was an almighty "clonk" and when I was underneath it a few weeks later I noticed that the nuts were missing from the engine mounts It's easy enough to check
I'd imagine he removed the nuts on the engine mounts so that he could lift the engine slightly.
He's probably just forgotten to put the nuts back on. I've done it myself in the past.
Bit of turbo probably caused a ringland issue or debris that went through the turbo after removal of pre-cat. Get a compression test. If you see up to a 45% loss on a cylinder but the car isn't smoking, using oil or feeling sluggish, then don't fix it.

Think you should have hit the snooze button a few more times this morning

I hope it's just that.
I'll have a look myself. Are they easy to see?

If the cam belts recently been changed it could not be refitted correctly and the timing is out, this would cause a slight rocking
Yes I did mention that to my mechanic friend.he's having a look on Monday. But he wasn't convinced.
I'm gonna have a look at mounts tomorrow evening. Fingers crossed.

Of course he's not convinced as it will be his fault! This is what I'd say the issue is.
The negative progressive thrust that is being forced upon the crankshaft during the 48.9 degree rotational mass is causing the double over head cams to become inconsistent during the fuelling process hence the rocking engine...................................
Oh wait, somebody has already gave a ****ing retarded answer............gutted
Surely a misfire due to timing being out (which can't be far out as it still runs) would the ecu no pull the timing to adjust? If it was a misfire would it not rock the whole car not just the engine?

I know.I did reiterate it to him.
I'm damned if I'm going to take those cambelt covers off and checking myself.
Not that I'd know what to look for.
It would be a tooth out wouldn't it?

My car shakes on idle, once warmed up, though none of the subsequent tuners have noticed it with several pointing out nothing is wrong with Billy.
People have reported similar losses to mine and mentioned horrible running with smoke oozing out of the exhaust.
That's it with Subaru though, always different symptoms and opinions.
There's 2 or 3 people at a push on here who know technically how a VTA makes the car over-fuel. So far none have clinically told me why a blanked DV causes rich running and a recirc doesn't.
