    the truck has a gas motor in it with the fuel injected carb. it has a leak in the exhaust manifold because it is missing the gasket but I don't know if that could be part of the problem. the other thing I thought it could be is the injectors could be bad or clogged. the idle is turned up on it to try and keep it running.

It sounds like gas starvation or if deisel it could be air in the system, either gas or deisel there could be a possible pump problem, if gas it could be ignition timing is out,

    this sounds like it has what we call a single point injection, ie one injector that is inside sumthing that looks like a carb, i dont think the exhaust gasket will make any difference, only to the oxygen sensor on the exhaust, i dont think that would make it under idle, you do however have a valve called the idle-up valve which may be causing your problem use my email i will send you a basic layout of your engine....hope this helps

Break and battery light stays on all the time


sold all over earth, what country> we cant guess this....
don't break the brakes....!!!
my guess, you meant the
brake lamps are on keys in pocket. and the battery lamp is dash(charge) glows, keys in pocket. right?
and battery cable kills all this illegal states above. sure.

86 nissan PU.
720 PU>? Datsun>?
or D21 Nissan ( 1986 Dat-SUNS became NISSANS. in USA)
Model years 1986.5 (second half) and later were called Nissan Hardbody Trucks, chassis code D21.

D21 are called HARD BODY trucks. mid year changes.
so???? which is yours.

as you might not ,know , the models are wired diffrent by different exact models and country.
long ago , i had the 86 with the VG30 V6...

so i will roll the dice and answer for
D21
ok?

things off stay on, 101
bad wiring, hacked in wiring, radios,alarms and other things.
all can cause this..... its old and is common on old cars.
but if wiring is not hacked, (id see that in 10seconds in person)
no hacks.
gas engine car not diesel.
USA 86 body
brakes
Im looking now at the schematic and this car has a hot at all times
brake lamp switch. (foot pedal switch)
SO only a bad switch can cause this.... period
now the dash charge (battery ) light stuck on.


my online source ,has the alternator system missing.
so can not comment.
the lamp gets its power from the key switch
if the key switch fails , all warning lanps glow not just the
charge.(battery)
so its not that
my best guess is wiring errors, that put power the the cluster
key off. id bet that is it .

wiring errors to the ignition output is side, key switched power is failing.

My 88 toyota camry wont accelerate when i step on the gas pedal


tests:

cruise at say 45mph ok?
if i accelerate , it bogs then catches up?
if i accelerate, it bogs and never catches up?
if i go WOT, wide open throttle it has full power up a hill after the bog?

these test , are the KEY tests.
this tells me what is wrong.
i hope the car is tuned up, if not , why no? the 60k mile done?

Acceleration problem


Could be a clogged fuel filter, could also be a slight crack in the throttle body gasket. get a spray bottle with water in it, set it to mist, while the vehicle idles, spray around the base of the throttle body, if it bogs down replace the throttle body gasket. Just curious, was it doing it before you changed the plugs and wires? If not make sure you have the firing order correct.
