yes only when I am stop and foot on brake. no check engine light yes I30
I would agree, the first thing I would do is clean the throttle chamber and adjust base idle
How handy are you?
I can tell you what you need to do to try to do this if you like?
Let me know, Thanks Jay!
I actually have the steps already to clean it...but I am not sure about adjusting the base idle. I think I am handy enough to do it...I am just nervous of messing up something with the throttle cable. As it seems delicate/easily to become loose. But thats about it....thanks!
You don't need to touch the throttle cables
Tell you what,
Just clean the throttle chamber
and get it running again, and then return and I will tell you how to adjust base idle
okay but I don't want to be cleaning twice as far as going back and forth with cleaning them or basically will it involve that? Taking something apart in order to adjust and clean the IACV?
Your only cleaning the throttle chamber
So all you want is a can of carb cleaner, a old tooth brush and some rags
Remove the intake boot to access the throttle plate
Pull the throttle open so the butterfly is open, and spray and scrub the throttle chamber
Top and bottom
Then spray and whip clean with a rag
Then put it back together
It will be a little hard to start after you do this, but lets see how it runs after you do that.
Then if we need to adjust base idle we can do that
I already did this...the car is running ok, just vibrating, but before it was causing the car to stall. Idle go all the way up and I needed to give it gas for it to start. You help me with this. Now I am going to remove the throttle this time, becuase it must be really dirt and causing the IACV to be messed up also
you cleaned the throttle chamber already?
you helped me with this, and the car ran much better after
Then we are at a different point now
but then I started to get this vibration after some other changes and maybe a 1000 miles later
Lets work on adjusting base idle now
and see if that helps
Do you know where the idle adjustment screw is?
no I do not. But to be honest I am thinking of taking the entire thing apart becuase I didnt clean i t good enough.
You don't need to remove the throttle chamber
You just need to take your time with carb cleaner and tooth brush to scrub the throttle chamber clean.
Let me get you a image of the Idle adjustment screw. Give me a min please
ok. I just couldnt get to the back thats why I am saying I need to take it off....plus holding the throttle open while doing it only gave me one hand to get in there.
Yeah, it's a bit of a pain, almost have a image for you, 1 more min
Lets get in there and clean the throttle chamber again
Then when your done
Unplug the bottom connector of the TPS
and turn this screw to adjust base idle
Then when set, plug the TPS back in
and lets see how it is
okay what do you adjust the screw with? and which way do I turn it? DO I turn it till its tight?
You turn it with a philps head screw driver
You don't turn it to tighten and you don't need to turn it all the way out so it falls out
You only need to turn it once or twice
You want to turn it counter clockwise to raise idle, and clock wise to lower it
okay. But what if I could get my whole intake system cleaned including throtttle IAV etc. Do you recommend this in this situation or in general. You seem to be not encouraging me to take the whole TB plate off, but I seen alot of people saying to get the best results that what you need to do.
Also which of those in the picture is the TPS? the brown or gray one?
Hold on 1 sec please
You want to unplug the gray one. I don't like to recommend people to take the whole throttle chamber off, cause if I recommend it and something goes wrong, I don't like being blamed if you know what I mean.
I don't even normally remove it to clean it
