Hi Liberty/Subaru owners, I have a curious cold starting issue, If i was to go out and cold start my 2001 Liberty 2.5RX with 256000k on the clock it would take about 5 seconds of turning over before it grumbled to an idle, then when i pull out from the curb there would be a flat spot and then away I go.
The curious part is, if I simply turn the key quickly on off so the engine cranks half or one revolution then turn the key again to normaly start, it starts imediatley. The flat spot is always there.
It is not expected for a service for another 5000ks and I did replace the spark plugs with a middle of the road plug which made no difference, I also over two tanks put injector cleaner in consecutive tanks, again no difference.
Any Ideas please.
