2000, 1.8i, Intermittent brief mis-fire at speed - stutters
Hi,
Recently my car has started to judder, quite violently but briefly at speed, the Engine Managment light comes on, it then drives fine (slightly more sluggish ??) for a couple - few minutes and the the light goes off and all is well again. It will then happen again at any speed, but not at all (maybe just once...) when stationary and idling.
Took it for diagnostics and it reported P0110 - Intake air temp high voltage and P0100 - Mass air flow sensore low voltage.
Replaced the MAF unit (£250....) , but it stayed the same and reported the same faults. Took back and a 2nd MAF was fitted (FOC) in case a faulty one had been supplied, but still the same and reporting the same faults.....
I have considered cleaning the throttle body and all associated breathers etc, but I thought that this was more associated with stalling / cutting out at low revs.... (have previously, 2 years ago, experienced this and solved it by a good clean out.)
Has any one experienced this and got any ideas ?
Thank you in advance,
frustrated.......

Hi Topbloke,
Yes it's a x18xe1. This sounds very possible..... I'm not aware of this and any information would be great!
Thank you,

well its is basically suppling a new earth wire for the maf sensor and the temp sensor. the original wire /earth point via the ecu fail , you would need to find the yellow wire from the maf and the brown cable from the temp sensor these wire join together in the trunking above the injectors, remove the cover, find the wires and splice into them a new wire, run this through the trunking and out near the ecu which is bolted to the engine, put a tag/eye terminal on the new bit of wire and using the earth wire bolt that is on ecu as a earth . this is a known fault and your local dealer should be aware of this, it is field remedy 2033 hope this helps

Hope this helps .

had car at autosparks he said he couldnt find
anything wrong with maps he thinks it might be
a problem with the fuel pump loosing pressure
as once it has started if youy turn the engine
off and then start it straight away it starts
1st time but when left for 60 seconds it takes
a long time to start any info would be very
helpful
thanks
