Cold Weather Issues
My 2007 Xterra has had issues starting in the cold weather, here is the situation:
If it dips below 40 degrees and my vehicle is not plugged in (Meaning a warmer on the battery, oil pan, and starter) it will not start unless I spray starting fluid down the intake.
If it gets below 10 degrees it takes it a while to start even plugged in.
If I turn the key on/off rapidly about 10-15 times, sometimes it will catch.
Also, while driving my tach will suddenly drop as if it is choking and then return to normal revs, but other then that it will run fine. No check engine lights, etc.
I have had considerable success plugging the vehicle in but once again these warmers are located on the STARTER, OIL PAN, AND BATTERY the ECM relay has been replaced, the fuel pump has been replaced, and the IPDM. It also has a brand new battery with 700 CCA and 10W30 oil and oil filter/spark plugs and wires. Any advice would be helpful!
