89/90 sidekick idle speeds 800/920rpm

I never did this to my 94 16V. How different is the steps in mine and does my regular DMM will work?^^^^

you can just use A dmm meter set to volts, and set it to 7v. 1/2 battery running.
if the meter dont mess that up, that is, as some do.
yes, the isc needs to be connected.
and in all cases back probed. the meter do both pins with needles.
its a 5 volt square wave signal there.
if if using a scope I just probe one side or the other and see the 5v signal.
I think one side is ecu ground but cant remember the color.
i should have took more readings with my scope, and got lazy.
but this solenoid does pulse 200 times a second, real fast.

that is a great TPS there...
