Correct timeing nissan ti 4.2lt efi - 1993 Nissan Pickup

2012 Nissan Dualis +2 Ti-L J 10 series 3 has a timing belt or chain? Pls let me know. Thanks.

Get car'scomputer scanned. It should diagnose the condition of your chain and they can tell you if ti's time to change it or you may leave it for some time

As a general rule, if it is making some weir noises, it's time to change it.

spark or cam?
all engines, have cam timing and spark timing.
do say which/
no matter, anyone can see this, at any time.
buy the FSM. (used or new) used off fleabay is easy
or login to alldata.com its all there all the time,,just look, and read.

surge, lopes, hunts, all same. but does it do this hot/cold or both engine temps.?????????
Im and expert on this.... done many and is related to EFI fuel controls
big time..... (ive even programmed Megasquirts to do this)
first the rules then causes.
Rule 1, The EFI controls idle at all times. so that proves.
Macro reasons.
1: EFI lost control. (stuck ISC?)
2: Engine is missiing (too rich, too lean or never tuned up)
3: or both, usually #2 causes 1 ,

there are ways to solve this riddle
my ways are simple
i test the ISC, see if it works, (unplug it or power it with 12v power supply, ) Id clean the ISC first.

this old car 1992 , scan tools are hard to find for OBD1 cars.
so cant look to see if CLosed loop is working, I can with a scope
but you dont have a scope.
you could put in the diagnostic check jumper and hope for an error code to flash out.
you can look as spark plugs (newones work wonder) and see
if its burning fuel correctly (like old school carb days)
black?> white tips>
all engine carbs and EFI all will surge when lean,.
all, and on EFI it will in fact try to stop the surge,
if lean enough the EFI can actually make the surge worse
is it tries desperately to correct the impossible.@!

that be surge.
i learnd that loping my mule one day.. LOL

OK then no problem is there.

replace timing chain on 1990 nissan pintara 2.4

I'm not sure for efi engines, but for carbureted GA series engines, there is an idle knob at the back of the carburetor that looks like a gear. Turn that knob and you will notice varying engine idle speeds. There is also an adjuster of some sort on efi engines but I'm not sure where to look. But! it is usually found in the rear portion of the engine connected to the air intake.

stop by local parts store (Autozone,Advance, etc) and have them do a free fault code test. They can print out a list of faults and clear the codes

you will need a repair manual

comes up as having both efi or carby what has yours got

if carby its a lot easier to bypass the faults to get it to run

will assume its EFI

EFI will be a problem if any wires have shorted
may have blow the large fuses in the engine bay giving power to the car


for both carby and EFI
pull the light fuses and relays out

check all fuses and relays in the engine bay cluster are not popped

starter relay and EFI ecu fuse are in the engine bay cluster

if the motor turns over
the fuel pump must be pumping fuel with pressure required to run the car to get fuel to the carby /or fuel rail and injectors
if you get that
only have to worry about spark
have you got a good coil arc and spark to all plugs

It's has a timing belt, also it's an interference engine, if belt goes bad it will bent valve's .
