engine not running right

**elite lee** · 13th November 2010, 09:03

want to throw this problem out to you lot for some ideas, i'm hoping somebody can help me.

a couple of months back i had an issue with my 2.2 petrol engine.
i changed the plugs and got a new coil pack. problem seemed to go away.
NOW IT'S BACK.
if i'm driving along at say 30 40 mph the engine runs great, put your foot down and accelerate hard to whatever speed all is fine.
the problem comes along when i'm driving around and i have to slow down a bit, like coming up to a roundabout, when i come out the other side it seems like it is missing for a while, like its not firing right. then it goes away and all is fine again.
i need a bit of help with this as it's begining to really get on my nerves now. dont know what else to look at for the problem.

cheers in advance

fuel pressure sensor or fuel filter worst end high pressure fuel pump some fuel pumps are covered under a recall has you car been to main dealer lately ring them up and ask about recalls ring two or three though as some dont want to know, it sounds just like mine mine was sensor was about 80 quid but they charged me 125 to find the fault and fit

Did you get the fuel pressure regulator replaced?

You need to get the fault code read... Was it engine light or the car & spanner light ?

engine light mate.

not got round to the fueling yet was going to phone dealers today.

Its the Car & Spanner light that would show for a failing Fuel Regulator or Pump, so guess you might be ok there... Engine light probably means something to do with air/fuel mixture or emissions control maybe not right.. But still, get the Regulator swapped out by dealer if they'll do it under the recall...

Is there anybody you know local to you who could read your codes, as a garage will charge you handsomly just to read them... (although the dealer will possibly inform you of the other codes if/when they change the fuel regulator)

my engine light came on when I had this problem when it went on tech 2 it said lambda 1 but put it down to pressure messing around and it over/under fueling as regulator packed up

i got the 2.2direct and it sounds like the same as mine did with mines it was the high pressure fuel filter and the fuel regulator got them both replaced under warranty and it runs better than it ever has . HTH

PLEASE CHECK EVERYTHING THE OTHER POSTERS HAS SAID, BUT,,if you changed the plugs/coil pack and the problem went away, but has now returned,,,, check your leads as well.
