on n88 toyota celica if i pull the plugwire on #2 cylander nothing happens,coulod it be abad fuel injector?

Answer 1

Insufficient information to say positively. However, if you have a bad injector (in ,most cases), - you will have a miss when accelerating, as well as idling. But suppose you instead , - had a leaking manifold (primarily into this cylinder), - then it would miss at idle, but seem to accelerate and run fine at higher engine speeds. The air leaking could be enough to make the mixture to cylinder insufficient for a "full power combustion" as you speed up engine, injector puts in a lot more fuel, - now the leakage is barely affecting the "total mixture", so the engine runs fine!

I you have a bad valve, (or broken valve lifter) you now are leaking air out on compression stroke, and you will see no actual change when pulling a plug wire. If you have some kind of damage to lifter, - or rocker arm, a valve may not be opening, so you don't get proper "charge in cylinder to make a full combustion mixture.

Answer 2

Well yes and no. Just beacuse you pull the wire, what does the plug look like. Remove the plug and look at it. Is it black, is it wet?
Do this remove the plug and plug in the wire. Lay that plug on some metal and crank up the car.
It will make a lot of noise but you can look at the plug and see if it is sparking.
If in doute, it is a cheep fex replace the plug first. If you have a test device called a NOID light ( you can get one from the auto parts store) Plug this light into the wire on the injuctor and crank it the light flashes the injuctor is getting the pulse needed to fire the injuctor. If it does not flash the wire to the injuctor mite be bad

Replace the plug first

Answer 3

yes could be or a handful of other things related to that cylinder. Are you getting spark through that plugwire?
