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

 

If I have vehicle in park or reverse or Netural the idle rises and its fine soon as its in drive thats when it happens

 

I have a picture of where the idle sits at but I have no clue how to post a picture

 

 

Mine does this as well. Today I adjusted the screw on the TB to open it a bit during idle to see if that helps.

 

Hey buddy can you show me a picture of where it's located and also what idle i should be putting it at?

I greatly appreciate it I have done everything today and I'm just real bummed out I've ran out of ideas!

How's your vehicle running now?

 

Did you disconnect the battery before you changed the sensors?

 

No buddy was I suppose to?

 

I have no check engine light nothing at all

 

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.
