    Question 1.8 sport rev problem

    I noticed a couple of weeks back that if I'm stopped the revs sit at 500 rpm but if i'm crawling in slow traffic and put the clutch down (say doing 5mph) the revs sit at 700 :s

    anyone else had the same problem? Car seems a bit lumpy too may I add

    check over the air flow meter, sounds like it could be on the way out

    I don't think that is normal tbh, I use to have this problem with my old 1.4, never found the problem tried almost everything from new stepper motor, to cleaning the thorttle body, in the end I just blamed it on the new battery that came as it suggests that once it's change if the ecu is without power for quite a long time it can reset all it's settings and start learning from the way you drive and so on.

    Anyway only thing I didn't try was the AFM as mentioned so maybe thats correct.

    right i got a brand new m.a.f sensor through today and promptly fitted it, but after starting the car up it started running badly and was splurting left right and centre. took it for a quick trip around the bypass out the back of my house and seems to pull ok and revs freely after 2,500rpm but anything below that and it feels like its about to conk out

    have changed it back to the old one and runs fine, even tried disconnecting the battery for half an hour but still had the same problem although it idles as it should with the new one connected :?

    anyone have any ideas? its definately the right sensor

    off ebay lol, was thinking that could be the reason why

    upon speaking to the bloke he says it came off a 1.8 16v zafira but assumed this would be ok, maybe ill just order another one and hope for the best??

    never ever buy either 2nd hand sensors or cheaper ebay pattern ones mate, they never resolve the issues/never work properly and add more confusion to the issue. if you want to PM me i have a perfectly good working unit as new and it is siemens genuine. you can have it for a few quid
