HI, My Vectra 1.8 is very sluggish at a cold startup, runs like it for about 3 mins then kicks in drives fine after that.

Any ideas

Thanks Keith

Were you able to sort this problem out? I have the same problem.

I now strongly believe that there could be a problem with the coolant temperture sensor circuit as it is linked to the engine management control unit. I plan to do a comprehensive test on it shortly.
