Guest sugarfairie Posted October 24, 2003 Report Posted October 24, 2003 Well it failed it's first MOT with me :D 2.0 Galaxy "N"Split CV boot, no problem there, fixed and sorted :D Failed on CO emmisions, had new airflow meter, bought the co down on the slow idle to a "pass" but the CO on the fast idle still too high, had something replaced at the back of engine ??? became lower again but not enough, now waiting for another new part not sure what it is now but it costs Quote
Guest SA Intruder Posted October 24, 2003 Report Posted October 24, 2003 Anna, could be several reasons. Firstly, it is imperative that all the vac hoses and the PCV valve are intact - they split easily. This is fairly easy to check. Secondly, the operation of the lambda sensor needs checking - not a homebrew job I'm afraid. I assume the airfilter is clean? Is the CO too high or too low? Quote
Guest sugarfairie Posted October 24, 2003 Report Posted October 24, 2003 lambda sensor is fine CO on fast idle was 1.71 is now lower but haven't seen my car since Monday... took it to the garage I always use and it has been moved to another garage where it has been plugged into a 'puter a code came up for the airflow meter so that was changed, I'm so sad my friend has bought me a box of choccies to cheer me up !The car was serviced about 3 months ago so air filter is spanking !! :D Thanks for help , any other suggestions greatly recieved !!Thanks ,Anna.

Guest SA Intruder Posted October 24, 2003 Report Posted October 24, 2003 And the vac hoses - they are always overlooked. Think simple faults first! Also, big failure point is coolant sensor. Get "garage" to simulate with a 330 ohm resistor. Measure CO. Coolant sensor may be high in value. Does the engine get to temperature OK? Must be correct for CO to be correct. Has the garage 'scoped the lambda sensor? The thing cannot be switching if the CO is that far out. Quote
Guest sugarfairie Posted October 25, 2003 Report Posted October 25, 2003 well the baby is back :D She passed her MOT with flying colours this morning, the problem seemed to be the secondary air pump, it had seized solid !So Quote
Guest SA Intruder Posted October 25, 2003 Report Posted October 25, 2003 So they refunded you for the misdiagnosed MAF sensor and the labour? Quote
Guest sugarfairie Posted October 25, 2003 Report Posted October 25, 2003 No refunds here I'm afraid, all parts fitted were deemed nessecary, and can't complain about the labour charges they only totalled Quote
