- 2001 Buick century
Ok, this car is driving me crazy. I have a 2001 Century with the 3.1 V6 that I just bought for my daughter. When it is cold out, the thing does not want to start very easy. Sometimes it will start, but at a low idle and sometimes it won’t start without feathering the throttle. I have changed the IAC, temp sensor (it was for sure bad), plugs, wires, air filter, fpr, fuel filter and the MAF. I also changed the alternator because the bearings sounded bad. I checked the fuel pressure and it was good at start and idle, around 43-45 psi. It did not seems to bleed off after sitting. Could really use some help.
