coolant change and the car takes forever to heat
well i did a coolant change about 6-7 month and i used NISSAN fluid with a 50/50 mix of distilled water ....
now the problem is it is cold and the car takes forever to warm up and lets the needle is in the middle of C ang H when i jump on the highways the needle drops just alttile over the c is that a problem?

I'd have to go with both air in the system and a bad t-stat. air usually causes the temp gauge to read hot, not cold. but I'm guessing you didn't purge air from the system when you did whatever work you did - so you probably do have air. a bad t-stat will cause the car to run cool just as you describe.

Dude it's your thermostat, it has nothing to do with what kind of coolant you used.. Your stat is stuck in the open position therefore letting the coolant circulate through the radiator all the time and overcooling so to speak..

I was changing my ECTS so I figured I would change the thermostat at the same time since it was the original 170,xxx miles and I didn't want to drain/purge the system again if the problem wasn't fixed the first time. So it was a combination of the two that fixed my problem.

Note: I had to stop on the side of the road for about 30 sec to get my car back to normal because it was so cold and the heat was blowing out cold air.

This does happen. The thermostat is stuck open. Since it may not be FULLY open, what it'll do is let the car warm up till it is normal. As you all know, the engine does cool down a bit when you are driving especially in cold weather like this. That is why when you start driving the needle will go down to cold. The cold air is cooling your car, and obviously the faster you move, the colder you're engine will be. Hence the moving back and forth of the needle from normal to cold and back to normal when you stop.

1) when i drive locally (new york city streets) the needle stays in the middle
2) when i jump on the highway the needle goes just abit over the "c" ....
so what your saying it is indeed the thermostat?

Also, please be more specific, coolant change in what, radiator or block or the entire system (flush)?

i did the heater core release (i think thats whats its called) when you hold the bottons on the auto climate control
release the screw in the bottom of the rad
then emptied the resevior
took a hose and blasted the top of the rad
then did a flush with the distilled water (didn't want any tap water leftover)
then i mixed the cooland with distilled water 50/50
filled the rad drove about 2 mile and topped it off..

Sounds like you'll be flushing again.
I don't know about the "heater core release" that you mention.
However, once you refilled, you let air into the system. You have to get that air out. So after you've filled up everything:
Set your heat on maximum. Leave the rad cap OFF. Start the car and apply STEADY STATE throttle to about 2k to 2500 rpm. As you do so watch the rad and soon you'll see coolant start to bubble just like a lava pit (air). Top it off, and start the process over again until you don't see any more air pockets popping.
It's slow, but that's how you make sure you don't have air in the system.
