So I gave it 2 weeks or more.. My car is acting weird... Ima make it short.... When I'm driving then come to a stop my idle shots up too 1600 rpm then slowly goes back down to 750 rpm... IT DOESN'T DO IT ALL THE TIME!, for example one day for half the day it was fine, the other half it was acting up.... What can cause this (fitv, icv, tps, etc) I think maybe air bubbles in coolant maybe??

Also happened twice so far.. First time I was leaving a store turned on my car turned on but then it felt like it wanted to die but it didn't then rpm shot to 2k then slowly down... Idk what's going on I do need the best advice, thanks!

 

service the iacv. it's more than likely sticking

 

Damn I just changed that too... From a auto car, guess I'll change it back and see if it goes back to normal
