Cold Starting

[Gerry M]

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??

Gerry got 9\'s all round on mine never a problem starting

I have 10\'s all round and no probs, mind you we are all considerably further south than you mate  :Laugh

Maybe give Pip a call?

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
