No acceleration limp mode?

Thank you for this post I had this problem and had to service the throttle bore all fixed :0)

2.0 diesel wont rev past 2500rpm and max speed 69mph no smoke runs fine just no power slow on take off and preforms as if a restrictor is in place

No trouble codes or any dash lights no repairs as yet

Hi,
Might well be worth checking the exhaust manifold switchover valve vacuum pipe. The switchover solenoid valve sits in front of the egr valve to the far right of the engine bay. It has a (usually) white plastic pipe which runs to switchover valve at the right of the inlet manifold. If split or holed it will prevent the manifold switching to the longer manifold length and restrict your rpm and power as per your problem.
Hope this helps,
Ed

Engine Performance problem
2005 Vauxhall Zafira Two Wheel Drive Manual 55000 miles

My engine is a 2.0 DTI, earlier I stopped for some lights but when I went to pull off again the engine warning light came on and the car would not rev above 1800, this was accompanied by the fact that the car would not speed up to anything over 30 mph.

Having left the car for about 15mins I returned to try and see what power the car had. At first it was sluggish and then what sounded a bit like an injector/turbo kicked in and allowed the revs up a bit.

Though light is still on and car is still very sluggish. Not wanting to drive it until I know roughly what the problem is before trying to get it into a garage.

Any Ideas anyone?

Engine Mechanical problem
2003 Vauxhall Zafira 4 cyl Front Wheel Drive Manual 97OOO miles

during the recent bad snow my car has giving me problems on 2 occasions when trying to get home. The problem being the air intake which points directly forward just to the right of the vauxhall badge in the grill sucking in snow which is building up in the filter box which in turn is thawing and impregnating the element, what seems to be happening is the water is then passing through the element and being inducted. Which is causing the engine to missfire, wont tick over, lack of power and will not respond to the throttle. Once the element is removed and dried and the box dried out the car drives as normal. Is there any mod that can be done to the air intake and as anyone else had the same problem. The car has never given me a problem either before or after these 2 occasions and only when ive been driving home in heavy snow

Hi I have got a 2.0tdi zafia and I have got me engain light come on and out and I loss all power so can you tell me what it may been so I can go and get it done thank you

On two ocassions on I have been traveling at around 30mph in 3rd gear and the car will rev loud and seem to lose power it slows to 20mph when I drop a gear it sorts this out but im worried and dont want to take the car on the motorway I think it could be sparks whats your opinion would cleaning out the system solve this with the stuff u put in fuel tank. Its a 1.6 and I have had it a few months.

When I have been travelling about 60 miles at a steady speed on the motorway, the car will begin to lose power.
If I release the gear and coast a bit then re engage the gear it will return to proper power. If I stop it will not lose power again for about 20 miles but then it will do it every mile or so. I can drive miles on ordinary roads and this doesn't happen.
Any thoughts?
