Hello all,
It's been a while since I have made a post in this fourm. Since I graduated to a 4th gen v8 4x4 haha. But I need some advice on a possible IAC replacement on my old truck (1998 4runner 3.4 2wd) I ended up selling it to my close buddies girlfriend and she has been enjoying it since. I still get to see it often which makes me happy. It Was sad to have to sell but I needed the money for my 4G. But anyways to the point. She has been having issues with her truck maintaining idle usually only on start up. What happens is you start it and it starts up good and fine for a second or so but then will either die or it will have a really low idle like at 400 ish rpm. I can hear its a bad low idle because it doesn't sound right. The truck will function otherwise fine. It's random when it does it but to get it to run normal you just give it some gas and spike the rpms above 1k + and then it winds back down and it acts and runs like normal, no low idling afterwards. When I had the truck I did a whole overhaul while doing the valve cover gaskets (knock sensors, clean the carbon from the intake plenums, new injectors, spark plugs etc.) One of the things I did during that job was remove the IAC from the throttle body and cleaned it to the best of my ability. But I am starting to think that it is going bad and that is what is causing her hard start / weird low idling issue. So what do y'all think? I think it is the IAC and I read a couple threads on here of people who had a similar issue who said it was the IAC. But I want to be sure it is before she drops 150-300 on a new one to try and fix the issue. Thank you guys
