cylinder problem

[90runner]

92 toyota 4runner, 3.0

Missing on a cylinder, I am not sure what it is, Maybe a stuck fuel injector or ??? I just put all new spark plugs, air filter, tried fuel injector cleaner, What do you guys think?

 

[Toyotanut]

what about spark plug wires?

 

[Ashes]

Distributor cap and rotor? Bad injector wires? Valve problem? Bad rings? Could be lots of stuff.

Burnt valve?

 

[Toyotanut]

have you been able to isolate what cylinder?

 

[90runner]

i can try that

Not sure what cylinder, Yes i know it could be lots of stuff. I will test some more things like the distributer and i dont think it is a burnt valve, ir bad rings cuz it doesnt smoke,
