the reason your 1uz makes that clicking noise before it starts is because one of the throttle body sensors is not on properly and causing it to mess up, remove it and put it on the right way, got rid of my clicking noise as soon as i did it, i think its the throttle position sensor if not its the one next to it
@pushhrodd01

Yes that’s actually your traction control system. The throttle body flap closest to the airbox. I just unplugged it and it went away. I don’t want traction control anyways

Going to try this thank you bro any reason why my sc400 dies when I turn the ac off while driving and come to a stop
@pushhrodd01
@pushhrodd01 4 месяца назад
Yes bro this is why. That little valve controls your idle when you come to a stop or in park. So if you do this and unplug it it will work. If you have any questions please comment on here and I’ll reply. I will probably make a new video explaining this better.

Could this explain why mine rough idles? It rough idles horribly to the point of the engine feeling like it’s about to jump out and walk home.
@pushhrodd01
@pushhrodd01 5 месяцев назад
Yes. If it’s only at idle then yes. If it sputters while driving or flooring it that’s a different issue.

I would buy new if i were you. It’s $500+ but it’s worth it. Junkyard ones are 25-30 years old and are going to break again.

Ive tried this trick with both the original ICV and a new ICV and both have still had the problem of jumping from 1500 rpm to 2500 rpm, ive tried a full and one and a half turns on both but neither make a difference. any thoughts on maybe why this would be happening?
@pushhrodd01
@pushhrodd01 3 месяца назад
Really?? That’s very strange. Try turning it all the way out to where the plunger will be fully extended out. The car should stall out. Remember you have to leave it unplugged. You can’t plug it back in. If the iacv is unplugged and not moving there is no way for the car to revup.

My idle jumps a little up and down and wants to stall when stoped at a light will this fix that issue ?
@pushhrodd01
@pushhrodd01 6 месяцев назад
Yes that’s definitely this valve. The valve is starting to malfunction. You can either find a new one or do this and bypass it. Adjust the valve at your will. If you do it and your idle is too high spin it 1.5 turns from the starting mark.

Mine was jumping up down, i cleaned this thing now it starts perfect then warms up or on traffic lights sits on 200 -250 rpm feels like want to die. What it could be any suggestions will be appreciated 🙏🏼

I know something that will help raise your idle is remove your throttle body and give it a very good clean. It raised my idle about 450rpm I was doing the valve cover gaskets and I took it off and it was absolutely caked and plugged up. I soaked it in brake cleaner and let it sit and got all the carbon off of it. The throttle body normal lets a tiny bit of air in the intake. Even when fully closed there is a small crack to let air in. Mine was completely plugged. Remove it completely and give it a shot!

You keep it unplugged? I’m confused does it fix the issue with it unplugged because it’s not telling the system to open and close the valve in the IACV?
@pushhrodd01
@pushhrodd01 4 месяца назад
Yes. Because you are manually turning the valve to stay open at one location. That location provides perfect idle. If it idles to high or tow you can spin it another 1/4 turn to get it where you like it. If you plug it back in since the valve is not working properly it will just glitch out and open and close at the wrong times which will cause a bad idle again.

@pushhrodd01
@pushhrodd01 4 месяца назад
@@toeneehonestly I believe I eventually went to 1 turn and then another quarter of a turn because 1 turn was like 950 rpm’s which was a little too high for me. You just have to play with it and set it where you like. I recommend in between 1.25 and 1.50 turns.

Hey so mine idles about 1,100rpm... i recently had the ecu rebuilt and initially thought it was the ecu re learning, could this be the reason why im idling so high?
@pushhrodd01
@pushhrodd01 3 месяца назад
Was it doing it before you got it rebuilt? If not then yes the ECU could very well just be learning the idle. If it persists after 100 miles I would definitely say it’s the idle air valve

The info is appreciated but this is more of a rig, not a fix. Wish the damn part wasn't so effin expensive...ridiculous!
@pushhrodd01
@pushhrodd01 2 месяца назад
You’re right.. I’m going to change the title. The part is around $600 USD which is ridiculous and you have to swap out the whole assembly where it mounts as well as its different from 92-94. It’s just a magnet with roller bearings no idea why it’s so expensive.
