    Default Car feels a bit sluggish

    Lately my vec seems to be getting progressively more sluggish under acceleration from rest. It still hoofs along at motorway speeds+ but the acceleration seems way down on what it was.

    I've cleaned the EGR valve out [it was as sooty as hell] and it seems to be operating as it should. I also cleared loads of cack out from around the inlet manifold/EGR connection. This was 'orrible black sticky gunge so what it's like inside the manifold gawd only knows!

    Is it possible the swirl flaps might be stuck open? I haven't had any error codes pop up so I have no reason to suspect this other than the rather sluggish acceleration, if indeed this is a symptom. Being a vectra noob, I have no idea how to check their operation.

    If it is the swirl flaps, is there any way of squirting in some cleaner of any kind to free them off or is it a manifold off jobby?

    Car has done 94K btw with full history.

    If not swirl flaps, any other ideas as to what might be causing it? Any suggestions would be much appreciated.

    Thanks folks

    Phil

    I had the same problem with mine (150bhp cdti), removed and cleaned the boost sensor and voila! perfect, back to full power. The sensor is quite delicate, i cleaned it with a toothbrush in my parts washer, took a while but it came up spotless.

    Service maybe?

    I know car can feel sluggish and then when they are serviced and cleaned out they feel a totally different car!

    Could be. Thanks for the response btw.

    It was last serviced by a dealer last June at 85K and then supposedly another oil and filter change by the selling dealer before I took delivery. [They could of course just have reset the service indicator!] According to mine I have another 9k to go before it needs a service.

    I'm really fretting about these ruddy swirl flaps due to the amount of clag I pulled out of the inlet manifold intake. I understand that if they are stuck open it could affect performance hence the question about if its poss to squirt some carb cleaner or something into the manifold to clean it out.

    I know beggar all about oil burners so I'm groping about in the dark here!

    Don't worry too much about the gunk in the manifold, thats just the way diesel's are. The sensor is on the inlet cam cover held on by one bolt, just unplug the wiring connector as well. The sensor is a sealed unit, the part you need to clean looks like a grain of rice on a stalk ( i think it's made of brass or similar ) held within a plastic cage to protect it. Go easy as it's quite delicate, as i said i used a toothbrush and some parafin to clean it. Shouldn't take much more than half an hour.

    Would using v power/ultimate diesel and or Millers help prevent the swirl/ boost sensor problem? I know sweet FA about the oily bits on a car so sorry if this is a daft question.

    I use Millers diesel treatment, i've noticed it reduces the amount of soot the engine gives out if you plant your foot on the gas. They claim it improves mpg, not sure about that though, although i know a couple of taxi drivers who swear by it.

    Hi mate could you post a pic of said item for me ? Im guessing it is positioned just to the left of the EGR valve and has a blue label on it ? My veccy 150 was very sluggish / hesitant so took egr out and found it full of crap and the inlet too . It seems 'better' but not convinced that im getting full boost low down the rev range so want to clean the boost sensor but not sure where it is ???
