hi

1st time on this forum hope you guys can help out.

have a bit of a problem ith my daughters polo.it wants to try and stall on deceleration/as you come to a stand still.the revs seem to drop to below 800 rpm and it is strugglig to tick over.it is a bit of a pain.we have swapped the throttle body for a scrap yard replacement but that has not cured it.

hope you guys can help out !!!!!

Welcome to the Forum.

There are quite a few things that could be causing the problems.

If there are no signs of a misfire, I would tend to start by looking for possible air leaks from the throttle body towards the engine.

Is it as bad or worse when the engine is hot/cold?

If you have access to Vagcom, that may throw some light onto the problem, if not, then I suggest that you have a look for said air leaks and re-post it if there is no improvement.

Regards.

hi thanks for the comments

it seems to be worse when warm. i think the auto choke keeps the revs up till warm then it has its problems

a friend has plugged in the fault code diagnostic in and it tell me lambda sensor may have a fault do you think this could be causing the problem

thanks mick

latest update

have replaced the lambda sensor and still no difference.

have also given all hoses attached to throttle body and air intake a good going over and cant seam to find any leaks,

helppppppppppppppp

cheers mick/katie law

Bump, I've got the same but prob but i can also hear like an intermittent hissing noise, maybe air being sucked in somewhere around the tb?...
