Title: Cold Starting
Post by: Gerry M on May 10, 2006, 12:38:34 PM
HI all

When my car was mapped & compression checked the plugs were changed to 9\'s all round intstead of 7 & 9. I\'ve since noticed that its harder to start when cold. Does this always happen with 9\'s all round??

Well before it fired first turn, now it fires then cuts out usually only idles after 2nd attempt, just wondering if the u/s O2 sensor could be anything to do with it. Only really noticed it in the last few days when its been really warm outside so maybe thats a factor in it, starts fine when hot thou
