Hi first Time for me if anyone can help.
Have been reading previous threads and similar to my problem but not exactly
Have a 2003 Vectra C CDXi 3.2l Auto.
When i start from cold it is cranky for about 15 secs then runs smooth and when I start it warm it runs fine for about 10 minutes and then will just lose all power and stop in the middle of the road. Will not start imediately but leave it for 30 secs and will restart as if nothing has happened.
Checked and cleaned throttle body/ICU, replaced fuel filter. Replaced a suspect vacuum hose.
Thought may have been fuel filler cap as a lot of pressure when taking it off but left cap off and no difference.
Has been doing it for a couple of weeks and seemed worse when only 15 or so litres in the tank but now is doing it no matter how much fuel.
Have noticed that when it cuts out will not even allow the starter motor to kick in in Neutral or park for 15 or so secs also. NOt sure if associated with the issue or not.
Am a little hesitant to start changing things on spec as in Aus even the smallest part for Vectras cost the equivalent of our GDP.
Also because there are not a lot around seems that the general mechanics have not had too much experience with this type so tend to only change stuff until they get an answer.
Delaers generally the same. Took to dealer for timing belt as i thought needed expertise to change. Came back with other issues and belt one tooth out.
Does anyone have any ideas??
