isc an tps questions

[boosted92]

is it possible isc can go bad an cause my car to idle super high until warmed up an also how do i calibrate me tps ive heard some things about hooking a multi meter to it but wat amount of voltage am i looking for an on which pins?? also i posted on here awhile back about my 92 awd cutting under a load of boost but only cuts if u mash the gas if u ease into it no cut is it possible this could be related to my tps or isc. any help would be awesome id like to get rid of that annoying high idle an the cutting while in boost.

How high is your idle? How long does it stay there before dropping any rpm?

[boosted92]

idles at about 3k for about 10 min until warmed up.

[BlaineEmerson]

Then after it warms up it goes to 750ish?

[boosted92]

about a 1000 is were it sits warmed up i tested tps its good an adjusted right so im thinking isc

[BlaineEmerson]

where is your biss screw set at?

[boosted92]

i have yet to adjust the biss screw i was going to ground thos pins an set that today an see wat happens.

[BlaineEmerson]

For sure set your idle and check your timing. 3k is a little high.. 2k and then down to 750ish is about right when its cold.

Are you sure you dont have a boost leak.

Fix your coolant temp sensor, and i bet this problem goes away (Cutting under boost, otherwise that issue is most likely a leak or somebody screwed your safc settings 6 ways from sunday)

One way to check that: Reset your safc to factory settings, zero adjustments.

Boost leak is easy too, $7 in parts at ace hardware and an air compressor WITH a limit valve (Adjust max pressure allowed out of the tank)
