what is the spark plug order on a 91 toyota corolla
J
I'm speaking of the plug wire order from the dist cap in case it's not
evident.
thanks

right, are 1,2,3, and 4.
If you are talking about ignition firing order, then that is incorrect. The
correct firing order will be 1-3-4-2 or possible 1-2-4-3.

I'm hooking up the spark plug wires from a new dist cap and I'm just double
checking the order as 1,2,3,4 left to right. I installed the new cap and the
car won't fire at all and I put the old cap on and the car idles fine but
bucks wildly and will stall out if I attempt to drive it.
Something is wrong but I don't think its the wiring order

I just went out and looked at my '92 Corolla.
You probably have the wires crossed at the distributor.
They are NOT in order. They are in the firing order.

That's why I've always either numbered my wires with tape or a marker or I
just did them one at a time.

I'll tell you what is wrong: 1-2-3-4 is NOT the correct firing order.

Did you have to force the wires on (I mean, stretch them, etc). The
wires should fit snug and with little effort if you have them all
hooked up correctly. Without seeing it I'd imagine all of the wires
are of different lengths.

No self-respecting engineer would design an engine with a firing order of
1-2-3-4 because the power pulses would be too uneven.

I had a problem like this with my old V8 Ford Torino.. That's why I
said the above. In the end believe it or not we got everything hooked
up correctly by following the length of the spark plug wires. Of
course we doublechecked ourselves with the shop manual later in the day
when we found it under the hood, which was laying in the back yard
about 20 ft away.

It is definitely a lot easier to put something back together correctly if
you take a good look before you take it apart. It also helps if you have
at least a basic understanding of how the item you are taking apart works.
I learned this lesson when I was around 11 or 12 and attempted to improve
the starting characteristics of our Lawn Boy lawnmower by taking apart the
carburetor. Who woulda thunk that sucker had so many pieces! My dad is not
very patient and wanted the lawn mowed so he put it back together that
evening, so I only got one day's reprieve from having to mow the lawn. I
learned a couple of things that day - 1) take a good look before you take
something apart, and 2) that Lawn Boy ran terrible even when it was at its
best.

I think I still have a couple of screws floating around from the moped
engine I disassembled when I was around that age. I still couldn't put
that confounded thing back together.

The advent of my using this thing while taking stuff apart has positively
saved my buttocks countless times already.

Yes but that makes the whole process so... mechanical. Where is the
fun in that?

I have a commodore with a buick based V6 in it that has a 6-1-2-3-4-5 firing
order, i'm sure somewhere in the the world is a 1-2-3-4 firing order.

The OP has an in-line 4 cylinder engine with cylinder numbers, from front to
back, 1,2,3,4, and the firing order is definitely NOT 1,2,3,4 for his
engine. IMO, telling him that it could be 1,2,3,4 because it may be that
somewhere in the world is not useful advice and is likely to reinforce his
notion that 1,2,3,4 is the correct firing order when in fact it is
definitely wrong.
In the case of an engine with 2 banks like a V or horizontally opposed
configuration, there is more than 1 way to number cylinders. For example on
a V6 engine, one configuration is to have cylinders 1,2, and 3 on one bank
and 4, 5, and 6 on the opposite bank; and another configuration is to have
1, 3, and 5 on one bank and 2, 4, and 6 on the opposite bank. Obviously,
cylinder number designation is a big factor in determining firing order.
Engineers determine firing order by trying to smooth out, or balance the
power strokes with the other 3 strokes of a 4 cycle engine. If the firing
sequence had adjacent cylinders on the same bank firing, the engine would be
unbalanced. In the case of the Buick engine you cited, note that the firing
order sequence is even-odd numbered cylinders, suggesting that the cylinder
numbering sequence is odd on one bank and even on the opposite bank. The
firing sequence does not have adjacent cylinders on the same bank firing.

Fair enough, I should have confirmed that Toyota 4 cylinder engines, be they
a S series, A Series, etc have a 1-3-4-2 firing order. I am yet to run into
a car with a 1-2-4-3 firing order.
My comment of "Somewhere in the world there is a 1-2-3-4 firing order"
however was directed at the fact the "No self-respecting engineer would
design an engine with a firing order of 1-2-3-4 because the power pulses
would be too uneven."
What i ment was that in a world where various types of engine are made there
are a lot of well respected engineers out there who do strange things.
What would make people think that it was ok to cut the V8 engine of a 968 in
half to make a 944 engine. (They DID)
Who would of thought it was ok to make and engine where the crankshaft was
stationary and the cylnders rotated. ( It was done in the early 1900's for
aircraft)
Is it ok to make a motor where the 2 opposing cylinders share a common
conrod and are hard fixed to the pistons because the crank pin runs in a
slide that allows it to move correctly. (Built in australia and is one of
the smoothest running engines ever)
They designed VR6 and its off shoot the W12. For those who dont know a VR6
Motor is a 10 degree V6 originally designed to fit in the space of a inline
4, the W12 is 2 joined together to make a 12 cylinder moter fit into the
space for a V6.
Who thought it would be ok to take a supercharger design in add a sparkplug
to make an engine. ( The rotary is a pretty good engine, whos basic design
stems back to a supercharger design for land speed record motobikes.)
Is it ok to make a motor where one cylinder fires then a gap of 312 degrees
then the next fires, and 408 degrees after that another cylinder fires. That
doesnt produce very even power cycles and it is as rough as guts unless it
has 2 balance shafts, even then it has a unique throb. At least one engineer
thought so as every Harly Davidson is power with that type of motor.
So maybe I miscommunited or maybe you took it wrong, but the fact remaings
that a lot of good engineers do some dumbass things sometimes either to be
unique or becuase they can.

attempts to get more power, efficiency, or smoothness, for fuel economy;
save design money or time; fit an engine in a specific space allotted to it;
save weight; or avoid paying royalties. There are sound engineering
principles behind most of the designs you cited, but I cannot think of any
reason for Toyota to design an in line 4 cylinder engine with a 1-2-3-4
firing order when they already had dozens designed.
