Engine runs terrible fouling plugs ( HELP )

[MR.Pizza]

Ok so I start the car and the whole car is shaking and it's blowing gray smoke out the muffler at idle and smells like fuel. It felt like it was running a cylinder shy so I pull the plugs. #1 is black and fouled and the rest seem fine. I replace the plugs and upload the base kal for the greddy with 440's ( what I Have ) and run the engine for 30 seconds. Same problem so I pull the new plugs and #1 is fouled and black. #2 looks clean as a whistle #3 & #4 look fine. So I do a compression test,

#1 150
#2 150
#3 150
#4 175

I'm pretty confused right now as to why the car is running like this, any ideas?

I'm guessing it's a valve but I'm not sure on how one would know. I guess time to throw the k24 in.

switch the coilpacks on #1 and #2, run the car for a little then check your plugs again.

Cool I'll give that a try.

Those numbers look low. But I would look at a dirty stuck open injector on #1. Swap the injector with another and see if the problem moves with it.

Yeah thats what I thought, I had 750's in there so I swapped those with the 440's and loaded the base kal. Then I replaced the plugs, still same issue.

do you have feeler gauges?
if you do, check your intake valves are in spec. (i believe its .09-0.11, but you should check a more reliable source) If it is in spec then check the exhaust valves, although it is less likely that exhaust gasses being trapped in the cylinder would cause this it is still possible.

edit: since your compression was awfully low, atleast that seems low to me, i have 210-220 on all cylinders, i would think this could be happening on all cylinders, weird that its just that one. You might have valve seal leaks or something, i donno much about what causes a low compression reading like that.

I've noticed in the past that i've gotten very different readings depending on which tester is used, my compression has always read around this level though. I just noticed my marshall fuel gauge is jumping around alot more than I remember seeing before, is this an indicator of something?

#1 plug fouled up within 30 seconds, car shakes seems like somethings up with that one. Crap.....

check the DIY on valve adjustment
it could be the valve lashing on cylinder one.
Do you have any codes? cylinder 1 misfire im assuming.
If the valve is too shut on the intake stroke you wont get enough air to ignite the fuel and then on the second intake stroke you'll burn so rich that you'll foul your plugs..
When the cylinder 1 coil pack is unplugged does it run any different than when it is plugged in?
my logic being that (atleast with a plug thats not fouled yet) you're igniting every other otto cycle, so with the spark plug out you wouldnt ignite any and the idle would get choppier or smoother, im not sure which.

Yeah I'll pop the cover off and check the valve lashing, I'm not getting any codes but it sure runs like it's not firing correctly.
