Low idle after vehicle warmed up
Hey guys hows it going?
I am having a low idle on my 2004 dodge sx2.0 sport when vehicle is warmed up the idle sits between 500-600rpm the steering wheel begins vibrating and you can hear a rattle or vibration coming from the engine under the hood.
I have had motor mounts replaced 1 yr ago
I have changed my spark plugs wires to ngk
I have put brand new champion plugs gapped at 35
I have replaced the TPS & Idle Air Valve didnt make any change
I have cleaned the Throttle body
When I turn on my AC my idle rises at 900RPM and vehicle runs fine but its now winter time I cant use the AC during winter to get rid of that problem.
This issue btw doesnt happen all the time which im at the point now I have no idea what the problem is
I put lucas fuel treatment in gas tank as well changed engine oil.
Im really puzzled any help would be greatly appreciated!
Thanks

I'll try and get a picture of it tomorrow. It is on the underside of the throttle body near the throttle cable. It's a brass colored 4.5mm screw if I remember. Tighten it (clockwise) to increase the idle. I had some errands to run after working on it so I haven't had a chance to see if it has made a difference or not. I'm just going to slowly keep tightening it to raise the idle to about 650/700 if I can.
