Hi all,

Had a search already but couldn't find any related topics.. Brought a clubby estate today, got it running but the engine hesitates when I rev it... The car is SORN and I'm on a busy road so ain't had a chance to drive it. If I press the accelerator the engine struggles to rev, the engine does eventually catch up... Any suggestions? Ticks over happily.

Fuel pump is fine, it has a Fuel pressure regulator, I've not seen one of these before, I'm wondering does this need tweaking? Can they be tweaked?

Apparently it is a metro turbo engine, or so I'm told! How can I identify what engine is in it? Do they have numbers on them like mini A series blocks?

Any help appreciated please...

That's a new topic for me, it's my 1st turbo... I'll google it now and investigate.

Could you elaborate please?

I'd find out if it's really a turbo, look down the back of the engine and there should be a turbo there!

Is there any oil in the dashpot?
Usually this problem is caused by lean mixture.

Is it old petrol? Could be the problem, normaly a turbo is easily visable and had big pipes and tubes around the engine bay. Fill the tank and use some "Redex" petrol/carb cleaner (I personally find it very effective)

Also see if the dashpot piston has resistance when pushing it into the dashpot, if not it needs some SU dashpot oil ( >£10 on eBay)

My knowlage of turbos is very limited, maybe if it is a turbo, someone in here can help you with that. :)

Joel.

Hi again guys,

Yep, there is defiantly a turbo there... Put some new fuel in it today, left it idle for for almost half hour and already it does seem better.
Still slightly hesitating but a big difference in yesterday's performance. The car had been sat for a long time without being started.

I will check out the dash pot tomorrow and see if any problems are obvious..

Cheers!

If its had been set for a while, fuel tend to leave gummy residues that screw up fuelling. I'd fill up with quality fresh fuel and pour about a pint of paint thinner in the tank if i was starting a car the was stored for about 1 year.
