Weird 4A-GE idle problem
Posted: Wed Jul 18, 2018 9:08 am
Hello,
I have 4age tvis in my toyota carina, and the idle is making me nuts. In warm summer days it drops down to 500rpm, but when i put heater to warm position, idle slowly raises to ~900rpm. In winter car idles about ~1100rpm but drops wery low if i let it run and sit still. It works good, no misfires or anything like that. I have burped coolant many times, adjusted tps, new oem thermostat, timing was good, no CEL, iacv cleaned two times, i boiled it that i can see it moves, it does. Can coolant temp sensor be failing somehow?
