85 ae86 gts not running right, injector?

[Comrade_charlie]

I checked timing its fine. then I unplugged each fuel injector to make sure they were working and when I unplugged number 2 it didn't make a difference in how it ran, It idles at 1200rpm or 1300rpm and the motor shakes back and forth(not firing on all cylinders), every other injector that I unplugged clearly made a difference but number 2 might be bad, or could it be a spark plug... Ill go pull the spark plug out. Ill pull the cap of the dist. too.

The ae86 uses a o-ring type injector right? I hate barb type took me forever to replace the injectors on my 300zx, they are barb type.

what injectors can I use, I heard 7mge injectors are identical. I think 295cc but thats just what I read on forums.

ok took out the spark plugs, the look find, I unplug the 2nd one, and start the car it runs the same, I unplug the 2nd fuel injector it runs the same...

And not there is water leaking from the passenger side of the motor, It looks to be coming out of the lower radiator line thing that is connected to the water pump(thermostat housing where that gasket is, hopefully its the gasket, I don't have much money for this car.).

I unplugged the 2nd spark plug wire with the car running and it arcs or sparks when I get it close to metal... Could the spark plug be bad and look good?

It has 220,000 miles, Im thinking its the injector...

Im pretty sure my injectors are 209cc, can any one confirm that? ive been searching and have not found a site that says "85 gts has 209cc injectors". I think i found some for 25 dollars, I think im going to buy it...

id be doing spark plugs and leads 1st, (generally the cause of a missfire) then re-inspect,

What's the compression?
Does the spark plug spark?

[Comrade_charlie]

I need to do a compression check(I totally didnt think about that) and ive checked if the spark plugs spark, and they do... Ill probably just buy a new injector or 4 new ones and go from there.

what is ignition timing supposed to be on these cars?
