2005 V6 3.2 petrol treg, I have followed all the forum instruction shy of replacing the fuel pumps. Got her home via a tow truck after refuelling and the 30sec stall started, have replaced the fuel filter and now will run fine then 30sec revs drop and then fires back up to over 2000rpm runs again then does this a few times then dies...sounds like a lumpy v8 when the revs drop. any suggestion on what this could be??
