Hi guys
today when i left work my engine managment light came on and stayed on
recently the car has been changed over to LPG will this have caused the problem , the only other thing iv done in the last few days is put oil in the engine and top up the radiator
the car is a 2005 WRX
any help will be appreciated or if theres any one in nottingham i can take it to get the fault read
thanks

 

Updated
cause was misfire in 1 and 3 probelys cos running rich on LPG

 

Might be worth checking the neutral position switch on the gearbox to make sure that isnt giving a false reading of misfires.
