It has been stated light to moderate drinking is good for the heart.I just read that either can cause heart problems.Which is true?

These signs are listed as possibly early warning of a heart attack, but may commonly occur in other conditions, eg a middle ear infection. So he must get expert advice.

I think the GP being unsure, but prescribing drugs anyway, is a very unimpressive medical performance.Ask for a referral.

With that history your husband should have a heart checkup. At the very least it is good to rule out that possibility, and to establish a baseline history for him.

The clinic will probably take an ECG and ultrasound, and then put him on a treadmill to cause moderate stress while monitoring closely. They have a formula to calculate the max heart rate allowable.

Meanwhile get a checkup from a ENT specialist to look at his middle ear.

I do hope you have access to reasonable health care, as so many don't these days.

2005 Frenza, Daewoo wonder box, and no engine of the 5 stated
Deawoo can sell them in usa so suzuki tried and failed too.... sad.
now that is a challenge. (like doing a cross word puzzle, cut in half.)
no, you do what the SUzuki fsm states.
the factory service manual.
there are test to do, the ECU does not have AI yet.
it takes a tech, to do test to find cause, a live human still.

the key to codes is to learn what the test does first
and how it fails, what did the ECU see at the failure.
this is called critical thinking, knowing that some tests
that failed are really caused by the other failures.

my online source fails to list 488s. sorry.
if that really is a EGR test.
there are many ways it can be done,
vacuum drop ( can be other failures disturbing vacuum and egr is ok)
EGR pot resistor, read back failed.?
EGR coils shorted or open. checks.
EGR map sensor , reads wrong. (lots of causes and tests)
or the EGR paths are blocked the exhaust path..

so read the manual, i dont have,,im not popping 4bucks for you.

https://suzukipitstopplus.com/Category/3-suzuki-service-manuals.aspx

even bouncing vacuum can make EGR fail.
lots of causes.
if i had the FSM print out on 488s, i can state all tests to find true cause.

True/False and dangerous. Though pickles contain a high amount of calcium which is necessary for the envelopment of bones and teeth. Pickles juice contains a high amount of acid and salt. Acid can eat away at your stomach and esophagus lining if abused. The excess salt can run up your blood pressure , and cause kidney problems.over time..Don't believe everything you hear. Most people need a good course in nutrition and basic anatomy so they can make good choices.

It is not recommended to take a headache aspirin tablet daily as it may affect the stomach lining and react with medications that may already have aspirin as an ingredient. However there are coated low dosage aspirin on the market specifically designed for heart patients. go on line and type in google -- low dosage aspirin tablets for heart patients and read all the various pages then consult you medical practitioner. Under no circumstances should you self medicate as it can cause more problems than what you start with

The CEL is only for smog , here USA, nothing else really.
the only way to see ALL errors, is to use a SCAN tool.
the scan tool shows ALL, all DTC errors, and live data.
I bet the MAP is good. (did you clean it ?)
the car has many engines opted, , not one can i guess.
so no engine, no joy.

was told means nothing, only fact matter.
get it fixed or learn to use a scan tool and read the FSM
book , see how to do the tests to find TRUE cause of symptoms , not one stated. here.

"the FSM is 4 bucks to read" factory service manual, ask.

An unloaded reading of 10 Volts on a 12 Volt car battery is considered dead. There are 6 cells in a typical lead acid (car) battery - each provides 2 volts. They are internally connected in series to provide 12 volts on the + and - posts. If one is cell shorted out - you'd see 10 volts if fully charged. Trickle charge the battery for 24 hours and measure voltage again. If 12 volts, bring it to be load tested. that will tell you the true state of the battery.

how too...... a real question.. how?
you remove them and replace them.
my guess you mean how to access them?
no year stated,
must be a A/T as most M/t have no lights, well some do but is just
for making console light up only (park dimmers)
on most cars, (FSM covered) you must dismantile the console
and can vary by year, and sub model of Corolla and country sold.
so... RTM get the FSM and read it.
or login to alldata.com for $15 clams and read to hearts content. like us.

depends
if vodka
*** on the beach
if whiskey
171 and monster
maybe yeagermister
these are hard drinks and will make you very drunk

lighter drinks
are cahlua and cream
white russin

and similar too many to list all

Many many things from engine faults to random signals.Get the car scanned this will give you information on what is going on. Just because it states - gearbox fault - it will not always actually be a true g/box fault (as I have found out in the past with these cars)
Hope this helps - good luck.
