Buy yourself an OpCom diagnostics unit, stop spending a fortune on parts without testing!
I got mine from
www.opcom.weebly.com
UK supplier, member/trader called Furby on most of the Vauxhall forums, see
http://www.vvoc.com/forum/forumdisplay.php?f=231
Use it to check the output from the Coolant Temp Sensor ( a common fault is the sensor keeps telling the ECU the engine is cold, causing overfuelling), the MAF, check the long term fuel trim and injector opening times etc.
Once you have the data post it up on VVOC along with full details of the car (engine code, model year etc.)
I should mention I have no connection to Furby or opcom.weebly, I was pointed towards his site by other forum members.
