Finally fixed my no spark issue car was running good...1 hour into my 5 hour drive temp gauge drops to 0 look at the aeroforce and its sitting at 180...1st fan kicks on at 180 2nd at 190...stopped at a rest area for couple mins started the car back up went up on high idle and wouldn't come down even with small blips of the throttle...finally after couple mins it will calms down and idle somewhat normal...on the highway runs fine no codes no hiccups...got real bad mpg the whole trip 22mpg...got home turned it off then started it back up same high idle...i looked at the front o2 and it was around 950mv and slowly dropping...once it dropped and started the normal jump all over the place it started idling normal...seems like the coolant sensor thinks it cold even when its hot...is that even possible since my aeroforce shows 180...also I am on the stock tstat but planning on changing that since I had the fan temps lowered
 


The coolant sensor is actually two sensors built into one if it is a three wire connector. Which I am assuming you have. One of the elements in it is probably bad.

There's the two wire one, but then that would mean you have a bad wire to the cluster or a bad cluster.
