  1. Hi all having major problems with my lupo sdi. When trying to maintain a steady speed there will be a slight power surge than it will drop back and moments later it will happen again, making it impossible to maintain a steady speed!! The car idles ok it only happens when diriving. My brother a former mechanic has changed the fuel filter, air filter, new injectors, and done a diesel purge in an attempt to solve the problem with no luck. The current thinking is it may be a faulty throttle position sensor or crank shaft position sensor .Anyone got any ideas ?? Its getting to the point when i'm
  2. Thanks again I'll let you know how I get on. Thanks again I'll let you know how I get on. Thanks again I'll let you know how I get on.
  3. Sorry for repeating myself in the above!!
  4. Ordered some carb cleaner for the throttle body. I'm unable to drive at a steady speed without it pulling slightly ! It's as if you have taken your foot off the accelerater slightly fot a second put you foot down a bit and it's fine till it happens again! Thanks for the replies
  5. Hi thanks for taking the time to reply. I should have said very slight fade!! No judder and idles ok.
  6. Hi has anyone got any ideas on this. When driving the engines seem to very very slightly fad for a second then pick up, the best way to describe it is feels like you have taken your foot off the accelerater for a split second then the power comes back. I have replaced the air and fuel filter and injectors this has improved things a lot but the problem is still there.

Last time my brother found a nick on the gear shaft which he smoothed.I read somewhere that a blocked breather can cause problems . thanks dave
