Temperature gauge cold then back to normal


You have to make sure the thermostat is working properly and is the correct one. Idle the vehicle for about 20 minutes and then feel the upper radiator hose. It should be hot to the touch. Drive the vehicle and when the temp gauge falls to 'cold' stop and feel it again. If it is much cooler to the touch than before the thermostat is defective or wrong.

2000 maxima has erratic idle on cold days and will stall out on extremely cold days. Also, have noted antifreeze leak (on ground) on those really cold days. Car runs fine once it reaches normal operating...


It sounds like an engine temp sensor is open.. When your engine is cold or anti-freeze is cold your ECU or ECM gets a signal from the temp sensor for cold engine start. It would make sense that it works fine when hot because the resistance on the sensor is a lot lower. Take an ohm meter if you have one and check the resistance across the temp sensor pins. When the engine is cold the resisitance should be really high. Start and warm up your car to normal temp and check it again. It should be a lot lower now. If not replace it. Hope this helps.

do u have a check engine light coming on? if not the plugs are not the problem a miss will trigger a check engine/service engine soon light, most likely you have a dirty automatic idle speed control motor.

Shifting problems


The transmission/computer is designed not to go into overdrive until it reaches a certain temp and I don't remember what the temp is. Mine does same thing and it has 250,000 miles on it. When you start your truck up do you start it and warm up in neutral? The transmission fluid won't flow unless it is. There is know way to force it to shift into overdrive until it warms to the set temp.

Hope this helps

2004 crvautomatic high idle on cold startup 1600rpm takes 3 to 5


Hondas are famous for this, my accord does it. This is normal UNLESS it still idles high after normal running temp. has occured. Watch your temp. gauge when it reaches normal temp tap the gas a little bit if the idle drops then it is fine
