In the morning it will crank and turn over but will die. It has gotten worse as we have gotten into winter. Once it has been started and ran for the drive to work it starts fine the rest of the day, but after sitting over night it returns. I have new O2 sensors, tps, iac. Any ideas?? (I have rev and keep rpm's to about 1500 for 6 or 7 minutes and slowly let it down and it will idle but has to idle a lil while longer or will die while coming to a stop.
