Engine light on scanned p0300 po301 and another 1735 or 1755 or 1765 not sure but ignition coil ouput #1

when did car last run ;perfectly? last month, last year, or don't know?
p0300 means all fail randomly (is the key clue here.
there are only 3 causes (engine,spark ,fuel) (bad list)
the P030x errors are all , bad combustion errors.
that means,
can be lean burn, misfiring or way way too rich or bad fuel.(old)
or weak compression on all cylinders below 150PSI WOT
bad spark on all. (spark must be good on all)
1/2 clogged injectors on all..(or some fail leak down tests)
so did not check LTFT, long term fuel trim?
check fuel pressure? to low or too high and not in spec range.
I bet P0300 pending's is not a lie.
most cars need to be hard driven to see all DTC possible.
some take 3 driving cycles to trip. so drive way tests are very limited.
is engine coolant at 180f hot? or more hot, if not thermostat is bad.
as all are that old if is.
24 year stats are junk now. even non linear or even stuck open/
stats that old fully capable of even being INTERMITTENT.
Scan tool hot. ECT = 180F? PID scanned, Ect.
only used real scan tools not $17 useless code readers,
the real too can scan any sensor on demand. called PID scans.
and see pendings never forget to check pendings.
at 180f hot engine does scan tool; show CLOSE loop status?
it must, if not fix that first. (and p0300 for sure)
front 02 sensors bad.
302 means cylinder 2 misfires, but I bet the all do if car driven hard and scanned at the same time. I never just scan parked, drive it hard.
if lean power will be horrible weak.
not told at all how it drives. and matters huge, what is seen odd.

P1189 Buick - Engine Oil Pressure Switch Fault PO301
Possible causes
- Faulty spark plug 1
- Clogged or faulty fuel injector 1
- Faulty ignition coil 1
- Fuel injector 1 harness is open or shorted
- Fuel injector 1 circuit poor electrical connection
- Ignition coil 1 harness is open or shorted
- Ignition coil 1 circuit poor electrical connection
- Insufficient cylinder 1 compression
- Incorrect fuel pressure
- Intake air leak
PO300 is just telling you that you had a misfire.

Did you replace the wires? What kind of car?

Hello and welcome, when the check engine light flashes, this means a engine miss that can cause damage to the cat. converter if you keep driving, you will need to have the system scanned for trouble codes, probably has a code P0300. a engine miss can be caused by spark plugs, plug wires, ignition coils, injectors or even a internal engine problem

You need to have the ecm scanned for codes. The VSC and TRAC OFF lights are one just because the Check engine light is on. Once you clear the code in the ecm they will go off too.

P0300
1.ignition system fault spark plug ign wire coil.
2.vacuum leak, inj fault.
3.high or low fuel pressure.
P0420
1.catylist eff low bank1- cat can be defective.
2.eng misfire, vacuum leak.
3.engine oil leak into the exhaust valve guide seals.
as for the warranty i dont know.
