Hesitation/misfire
Hi,
I've been trying to cure a problem I have with my scoob (MY00) and I was wondering if anyone had come across these symtoms before or have a suggestion of what the problem could be. Basically if I'm cruising on the motorway or A road (steady throttle, not gunning it, could be doing 80mph or 40mph) the car seems to start spluttering or losing power. If I put my foot down to try and acclerate through it it doesn't help. If I drop cog it seems to clear it's throat and off we go like I'd expect it to. The car had new plugs a couple of thousand miles ago as I thought this could have been the problem but it still does it. It also had new leads and and a MAF about 12months ago. I changed the MAF as it was cutting out when I stopped at road junctions but this was actually cured by cleaing the idle control valve with carb cleaner. I've done a search on scooby net hoping to find a similar situation and all I could find was an indication that it could be the lambda sensor? I run the car on SUL so I don't think it's bad fuel. Any ideas what the problem could be would be appreciated. Thanks |
Put a new O2 sensor in today. Won't know if it's worked until next week.

Sounds very much like a lambda sensor if its off boost.

i have much the same problem with my00.changed and tested the lambda and it`s not that.feels a bit like your towing a caravan until you get it going!!Pretty much given up trying to source the problem my self.Gonna save up and get the ecu sorted by someone see if that sorts it.

Just thought I'd let you know it was the O2 sensor (or lambda). I've done about 1000 miles in the last two weeks and it appears to be sorted.
Put in a universal one from a local motor factors. |
