i took off the sparkplugs of my turbo charge SiR and these are what they look like:



sorry about the pic but i think it's enough to see the condition of the plugs. i'm not sure what they really mean, am i running rich or lean? what should my plugs look like to be on the safe side?

by the way, are these normal resistance reading for plug wires:
#1 - 12+ k ohms
#2 - 10+ k ohms
#3 - 8+ k ohms
#4 - 6+ k ohms

is the resistance supposed to drop as the plug wires shorten?

Looks like the far left is rich and the other three are lean.

Man, do use a favor and change your avatar....she scares the **** out of me.

 

what cause the far left to be rich while the other is lean? by the way, the far left is cylinder #4 and far right is cylinder #1.

 

What kit are you running? FMAX?

Kill the avatar man.

 

it's NOT a turbo kit coz a kit cost an arm and a leg from where i live. it's just a custom turbo.

 

Does it use secondary injectors in the intake manifold before the throttle body?

 

what your fuel setup? FMU? what injectors? stock? perhaps 3 bad injectors, and 1 good one...

 

sometimes flow rate of injectors can have that effect? maybe need to be balanced and cleaned.

 

i don't have an injector on the intake.

here's my fuel setup:
vortech 8:1 fmu
bosch inline fuel pump
stock injectors
stock intank pump

i use the screwdriver test on each injectors and they all of them are ticking at the same rate. i thought i'll be ok once i installed the bosch inline but it seems there's not much improvement.

 

how bout the spark plug wires, is it normal to have a lesser resistance when the wire gets shorter from cylinder #1 to #4?

cylinder#1 - 12.+ k ohms
cylinder#2 - 10.+ k ohms
cylinder#3 - 8.+ k ohms
cylinder#4 - 6.+ k ohms
