They look the same to me?

Maybe I'm a noob, but pictures only doesn't really help me. I'm not sure what resistances/readings you are pulling. If it's a misfire on all cylinders, maybe your timing is off by a lot. Check the cam timing and make sure it is aligned with the crank timing at TDC. Then get some new plugs for sure. Those are useless now.

I'd start there and make sure there is no damage to the valves. Check the timing with timing light after you fix the timing belt. You can adjust it by moving the distributor.

Should definitely get you some where. My timing light is so dim I have to wait till it's dark out to use it haha.

never got new plugs tried a old set engine respond better but still stutters @ a low steady RPM not going pass 5500 Rpm without a BIG misfire low on fuel too also checked resistance on injectors which came out to be 0.01 ohms

What engine do you have in there?
Are you running an injector resistor box?

Are you getting a check engine light?

What setting did you have the meter set to when checking your injector resistance?
I am assuming you unplugged the harness so you are testing directly to the two pins on the injector.
Injectors should read 2~3 ohms if you have peak hold injectors. They require an injector resistor box.
The saturated injectors should read about 11 ohms.
So I'm guessing you either don't have the meter set up right or the injectors are fried.

Looks like you posted right when I was typing!
Turn your scale down one or two clicks. 2000 is too high.

Anyway, it looks like you probably have a 12 ohm reading.
That would be saturated type injectors.

Do you have a resistor box in place?
If so, get rid of it!

Adjust valve lash if you can hear it. That's easy, just a feeler gauge and a driver.

If your valve leash is actually quite off, too loose or too tight, it may end up ruining another set of spark plugs.

I was expecting different from the looks of the outside of the motor.

[QUOTE=Bassy_budz;49254619]

The third plug has a shorter tip than the other three. The shorter one is ls the longer ones
are for b18c/b16a.
