How do I test a distributor in a 1990 Geo Tracker?
It will not start.
Start at the spark plug end of each plug lead and check each lead is dry and not damaged. Using insulated pliers or insulated grips, and a new spark plug, rest the spark plug threaded section on the engine block. Crank the engine and look for a clean, bright spark. You might need a helper to do this. Repeat this for all the plug leads.
ONLY REMOVE ONE PLUG LEAD AT A TIME. Refit the plug lead your using BEFORE you remove the next
one. If there is damage replace ALL of them, then you get a constant spark on all the spark plugs.
Next, remove the distributor cap and examine it closely. There should be no cracks or splits In the body. The terminals inside should be clean, bright and shiny. Removing only one lead at a time check the connecting holes in the top of the distributor for damage or corrosion. If ANY damage or corrosion replace the cap.
Examine the rotor inside the distributor. The rotor should be undamaged and the metal terminal should be clean and shiny. If damaged or corroded replace it!
If it's an older 'points' setup check the moving points as they wear out over time. The more modern electronic distributors will need a specialist Auto Electrician to test the electronics inside it. Yours is probably the electronic type.

wont go to high idle
this is the IAC failing not TPS, the tps only signals to the ECU
that you are at idle.

How to replace the carbon on 94 geo tracker?
carbon (Slept 3 nights,(on vac 30 day)\
answer 1 wire at a time. or it cross fires.
my guess is you meant changing carbon core
HV spark wires, but the plug wells are like oil pits. (flooded) SUPER COMMON.
(not spark tips carbon-ed up. right)
get he MAG wires and win.! max life and better spark!!!
all G16b do this seen 100s and all C.O.P engines.
owners did not do full 60k mile tuneup
per operators guide, lost it have it ask.
the valve lash step, demands a new valve cover gasket set.
if not it will fAIL, it will,like pissn on a sparkplug
bam. like texas talk, i do...sorry
and a cam belt.. forgot that too?
that is fail 2 , in the woods,
or like train light in the tunnel.
not one of those parts last the life of engine
the real reasons tuneups were invented
and why planes dont crash (of ddumbb things like this)
tuneups on this engine, only make long walk home
on other engines, most DOHC. boom head valves bent or far far worse.

I have Tom Tom GEo 93 screen is flickers
Flickering displays are a sign of a failing backlight for the LCD. If device is still under warranty, contact for RMA (return merchandise authorization). If not, then the GPS is a bit dated and would be best to replace with a newer model with updated maps and Glonass satellite support. Repair not under warranty would not be cost effective

How to determine if there's spark on coil 1992 Geo Storm engine 1.6
Old fashioned way is to pull plug wire and listen for the miss. You'll have rough or slower idle. Be well insulated and not grounded or you may feel the shock. There is also a cheap tool you can buy for 5 ish dollars. It will connect to spark plug and end of spark plug wire. Basically you pull the wire off the plug and put this tester between the wire and plug. Start the vehicle then look for spark on you new spark testing tool
