So I just changed my coolant and noticed that my fans are only on if the air is on, or if the air is off..then they don't turn on unless the temp gets right on 230 then it cools down. is this normal? on the highway the temp is at 180, in traffic it jumps to 230 and the fans are on.

The normal operating temps should be 220-230. It sounds like someone may have installed a 180 degree thermostat in the car and did not reprogram the fans for the lower temps. Assuming here you may have purchased the car used? That would explain why on the open road the thermostat is opening at 180 and you are running cooler, but when you get to town the fans won't kick on until you hit the higher temps. Shouldn't hurt a thing. You can always buy a programmer and turn the high and low fans down 5 degrees each. But it isn't necessary.

When mine was stock programming the fans came on at 217f with a/c off.

That sounds exactly right. Bought it used with a 180 Tstat already installed. Thanks for the info
