97 idle fluctuation sensor check
i've posted before about my 97' that has an idle problem that is INTERMITENT..and basically to make a long story short. idle fluctuates as it wish's and it's the same amount as it would if you turned an a/c on or loaded the alternator. APPROX. 1-150 rpms. again--problem is intermitent. i posted abotu it before and people told me the icp sensor was probably bad. well before i go buy a new one and install it. is ther a way to be sure that is it? any way i can ohm it out or check it any how? OR does anybody have any other suggestions as to what could be at fault?
thanks again

you can unlug the icp sensor. or did they mean the ipr?
your truck will run with a unplugged icp it sets it to default mode.
have you invested in a hpx line?

you can see the steel braided line to fitting that attaches to head it also runs to the other side.
my truck idles perfectly smooth no fluctuation. it equalizes the pressure in both heads. the icp is getting a reading from both in a sense this way. instead of just one side. can be bought from tymar for around 30 bucks. try unplugging the icp. i drove with mine unplugged for a while doesnt hurt a thing.
thats the old boost T before the stage 1's.

The line he is referring to goes from head to head in addition to the stock lines.
Here's a link to a stainless steel version:

so i had the probelm today while idling in the drivewya-..went under hook and unplugged the icp sensor and the engines idle kinds stumbled and then smoothed out and was fine. this means the sensor is at fault..right? i'll try it a few more times just to make sure.
