hey guys
my 95 max has been really low at idle. it is at 400 rpms. i was at 750-800 rpms. just wondering if anybody knows how to fix this.
thanks

I had a similar issue that I hope is fixed. In the stickies there are write-ups on adjusting idle speed, checking the throttle position sensor (TPS) and cleaning the IAC valve. I did all three, in this order:

- pulled off and cleaned IAC. There was some black and brown crud on it, and a scary amount of the same visible inside the intake plenum.
- checked the TPS voltage and resistance (all good).
- adjusted the idle speed screw with the TPS disconnected. I think this was the actual fix.

I had recently pulled off the air intake, throttle body, and intake plenum, and something must have moved when I reinstalled everything.

 

Also check Throttle Body. Dirtly throttle bidy means - less air = low rmps. Clean it, there is a sticky in the How To's section, and then adjust the idle with the idle screw on IACV valve

 

where is the idle screw?

 

To the right of the hose coming off the intake tubing. Looks like this
