Title: Bizarre engine start
Post by: Johnny English on 30 May 2012, 18:40:43
Hi all there, the fate came at me in face of bizarre engine start. After igniton the engine starts as usual revs up to 1500-1700rpm but no idle and shut down... :-\ but I'm enough smart to play on the pedal and till now I could catch the rpm around 1000 and let it decrease slowly so Miggy finds the idle and ticking normally...Some weeks earlier misfired in lpg mode the lambda sensors and MAF sensor faulty was find as stored massage. Swapped all of them but could not clear the history despite of hard battery disconnection so now I'm not able to fix whether if I got the same codes again or not. I'm adviceless a wee bit...Any recommendation would be welcomed!    Laszlo

assuming its cold start , first port of call, air leak  :-\
 
how it behaves after the engine is hot.. is it playing up ?

No, after one minute running it works well!

personally I would still check for air leaks and change the gaskets as they are cheap.. and second check point ICV.. and later, ignition components and battery voltage..

The following makes me suspect otherwise:

     LPG
     MAF fault reported
     Lambda fault reported

The baove hints towards a poorly performing LPG setup which ahs driven the block learn values to one end and then raised codes.

The idle may well be related to this but also check and clean the breathers and idle valve for good measure.

Update : checked the way of air income and found this not too small split. And how did I manage to start miggy at all?  I don't know... :D :D :D
