I feel weak Should I reduce to half5mgI am age 90 Itake bisoporol anf it drops to 41-114

Clicking sound is the solenoid activated starting switch pulling in, then dropping out because of low voltage when the starter motor is connected electrically. When the contact drops out, the load on battery is reduced, voltage rises again enough to pull the solenoid switch back in and click. This happens four or five times a second and thus hear the "clicking" sound.
Only a load tester will indicate if battery is weak. Simple voltage testers only show open circuit voltage.
Load testers usually apply a 50 Amp load for 30 seconds. That 30 second voltage must then be compared to the battery's CCA rating, which gives you an true indication of battery's condition.
I suspect a load test will show the present battery to be weak or bad. If battery is five or more years old, it owes you nothing.
Best deals on new batteries is WalMart with free installation.

Something is obviously causing the engine to run hot or not allowing coolant to circulate. Take to a mechanic before more damage occurs.

I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

ever get a full tune up this decade? yes/no.
no , then what are you waiting for, some guy to charge you for new engine with only bad spark plugs>? or fuel filter? or air filter?
which engine, be the first in 100s to say.
most dont and expect helpers to be like god, clairvoyant.
or super man with 12,000 mile xray eyes, really?

2004 has 6ve1 V6 but not in a 2001.!
2004 last isuzu car here. became rebadged cars. GM
but the 2001 i think is a Rodeo, so says the wiki!

If the gas foot causes engine RPM to raise super high over 3000 rpm and not attendant car speed increase(mph)this is called transmission slip. is it slipping , no? then its a weak engine
easy no ?
we dont have these parts in USA>????? change pluck and tortle mouth if fact , perplexing to read....

weak engines> facts. all.
reduced power has any causes, over 50, so will not cause you to go broke with my silly wild guessing as seen here. every day.

the engine power can drop from 3 reasons.
besides a bad engine, 25 reasons there.
in physics they are, (a good engine with full compression tests ok)

1. lack of fuel (low fuel pressure)
2. too much fuel, flooding misfire.
3. and huge list of causes of misfires
4. lost power misfiring is violent and engine shakes. (bad spark?)
5. lost power feels only like dragging weight we call bogging.
6. and is usually fuel pressure loss. or weak injections.
7. bad sensor to the PCM , scan the PCM and win.
8. lots more, but no thesis today, just a short list.

so you have 2 choices
get it fixed
or buy the tools and DIY ,
fish or cut bait... we say.

my guess get it fixed, the tools can cost.
$20 each
and if need to buy them all $100 (buy them as needed an win)
and a $100 scan tool.
or barrow one, buy one or ask any shop in town, hey mista,
can yous, scan me car for free?

now my wild useless guess
get a tuneup.

Usually means the engine bearings are worn out, or the oil pump is weak.
As the oil gets hot, it gets thinner, which reduces pressure. When the engine is at idle speed the pump is not pumping as fast as it is at highway speed.

Most OE factory wiring is marginal as far as amperage carrying capability goes. They installed wiring fine for the stock bulbs and switch. A lot of vehicles send power to the lights..head and running...through the light switch on the dash. This causes it's own problems as switches are the weak link in the lighting system.

If you run 100watt bulbs you will need to power the bulbs via a 40 amp relay switched by the light switch so the switch does not carry the amperage load through it's contacts.

Doing so will reduce the voltage drop to the bulbs as a 2 volt drop will cause the bulbs to be only 75% as bright as they would be with the full 13.5 volt running voltage..

You run a fused wire from the battery or power distribution block to the relay that should be mounted within 6 inches of the closest h/l bulb. Then from the relay to the head light bulb/s. The front and rear running lamps can remain as factory as they are low amperage draw and original light switch will work because you now no longer run power to the h/lamps through the switch.

Search the www for schematics for relay switched lamps.

its jamming,
or motor weak.
feel it by hand , motor disconnected. if feels good, then
its a bad motor, (weak) or not getting full 12vdc on command.
1 min, voltmeter check, and latter dispelled.

Well firstly it doesnt need a catalyc system pre 1992 and you will get this reading because you have by passed the mass air flow sensor causing a weak mixture ,so please stop messing around with what you obviously know very little about and leave any major problems to qualified people ,i mean would you try doing a solicitors job or a doctors job .A motor vehicle is a complicated bit of kit on modern day vehicles even this old banger that is now over 20yrs old and in some countries would be deemed as as a collectable classic .Has it passed its yearly mechanical inspection in accordance to the euroepon directive regarding motor vehicles of this age ?

If your power steering is whining you may just be low on power sterring fluid. I would check that first. If that is good your power steering pump may be on its way out.

There is a power brake booster in your system, but that should not affect if your brakes feel "mushy". I would look at the master cylinder, you probably need a new master cylinder they have a tendency to leak fluid past the seals as they age giving your pedal a mushy feeling. I woould also check your brake lines on each wheel to see if one might be leaking, this will give you a mushy feel as well. I doubt that is the case if you aren't loosing fluid however.

1- Battery may be weak, need to recharge.
2- At this car age, the solenoid has corroded contact causing high resistance reducing the current delivered to the starter. Therefore you could hear click coming from the solenoid, but not started.
3- Your solenoid costs about $41

Have You Checked Your Transmission Fluid?
Or Even Change It That Always Makes A Work Of Difference.
