evening guys and girls.

over the last few weeks i got slight hesitation maybe misfire when drive from cold and doing about 30mph in 4th gear and am woundering if any one has any ideas,could it be temp cooloant sensor or coil packs. i have replaced the lamdor sensor about 13months ago and replaced to coil packs 8 months ago.

any ideas would be helpful.

I would of said Lambda but seeing as you've replaced it maybe not. Was it a good make like Bosch you fitted or a cheapy one? I've known people to have s**tty motorfactor one's fail in no time at all but if it was a good one I'd say it's safe to rule that out.

If it goes when the car is warm then it does point to the green, ecu temp sender. They are cheap enough so a new one is probably worth a try.

I'm in agreement with Ryan, it sounds like the engine is being starved of the fuel it needs when running cold.

New CTS time, may as well get one from Pug, I think they are around £13 so not dear. Smile

did you reset the ecu after fitting the new parts?

also, try disconnecting the MAP sensor while its running. if it dies, its fine but if it carries on running it needs replacing

Wait until you are experiencing the problem reasonably bad and then pull over and whip the plugs out...

The colour of these will tell you a lot about what exactly what is happening inside the combustion chamber during the issue you describe and then you will be able to see whether it's running too rich or too lean at that point. Yes
