I've been trying to figure out why these spark plugs look like this for awhile now. I can't seem to figure it out. Here is a pic of them.

it would appear that you have two cyls that are way rich. i would check pulsewidth at each injector and maybe even swap injectors around to see if the condition follows the injector.

Well i found out what the problem was today. Did a compression test.

#1 160#2 0#3 160#4 0

When I got this motor, I never did a compression test on it.

oopsy, that motor prob has bent valves.

[capowered240]

That's what I'm thinking to. So I guess I have to pull the head off?

[s13sr20chris]

i would.

If they are bent, which they probably are, where can I get the valves from? I'll pull it off this weekend.
