#3 misfire and have done most under the sun

[96-Runner]

replaced injector gaskets
swap injectors
new coil pack swapped that around also
new plugs n wires

im out of options as to what it could be

 

[kolelt]

Maybe new coils in general ?

Are the plugs dual grounded ? What brand? What brand wires ? Do you have correct firing order ?

Do a compression test on all cylinders !

Are you loosing any coolant ?

 

[96-Runner]

i have the napa sparkplug wires so i believe nothing special as far as dual ground.
coolant stays steady no flux.
firin order is matched and nothing has been swapped as i got the misfire 2 stop for a period of time and returned
havent done a compression test have no knock or coolant/oil variance

A compression test, cooling system pressure check, and a check under the valve cover should tell you whats wrong. Unless its an electrical problem.

what would i be looking for under valve cover?

Get a noid light there cheap, check for signal to injector.

what would i be looking for under valve cover?

That would be a last resort after ruling out the others. (broken valve spring, bad cam lobe)

The noid light is a good idea.
