s14 sr20det Idle surge and high idle *HELP*

[Jonslams14]

Hey guys so I've been trying to solve this problem for a month now. Any help is appreciated

My car idles at 1100-1200. Will idle surge upon start up for about 5 seconds. When I turn my fans on the car will idle surge not stop from about 700-1400. Even without the fans on when driving and coming to a stop it will surge. Also if the car is idling and I touch the gas slightly it will rev right up to 2k and stay there for a second. When revving it higher like 3-4k it will drop down to about 1800-2000 rpm for a few seconds then go back to 1100.

My idle screw does nothing, , I've checked for leaks, checked my ign timing, checked my tps voltage. I'm stumped. bad aac? bad maf?

sounds like a bad or disconnected coolant temp sensor, this is the connector with two wires, not to be confused with the single wire dash temp sensor

[murffy]

the two sensors are right next to eachother, to the right of the throttle body

I actually just replaced the coolant temp sensor, unless my wiring going to it is bad. Keep in mind my fans are wired to a switch. Dual isis fans
