Checking Spark Plugs
Having engine problems after changing the B1S1 and B2S1 O2's, and I was wondering how long does it take for the new spark plug ceramics to darken so I can inspect them. Right now I have two hours on them, and they are all white still. I would drive it around more, but the engine is shaking so bad that I don't want to drive it unless I have to. Thanks

I know its not the O2's directly. But the shaking started 200 miles after changing them, on my way to college. I want to know how long it takes for the plugs to darken so I know if all of the cylinders are firing. I'm thinking it's a vacuum leak, or ignition coil/not getting enough spark or something. But until my friend can come over to see what codes I are on the truck now, my only question is how long does it take for the ceramic on the plugs to darken so I can look at them.

That wouldn't give delayed onset shaking after 200 miles would it? Seems like crossed wires = immediate symptoms

Sorry I didn't specify when I chanced the plugs. I changed the plugs the day after it started shaking. After reading more, I think think the problem is when I cleaned my MAF(day before problems started), I got some of the cleaner in the IAC. But the plugs should darken in a few minutes?
