there is lots of white-ish smoke coming out of the exhaust. I saw some moisture, and because cylnder4 is expells dense vapor when the plug is removed, I think the fuel is not being burnt. At first, sparkplug4 was major black. But now, he doesn't turn black anymore. When I unplug the fuel injector#4, nothing happens. BUT when I unplug the others, 1-3, it makes engine shutter. So I am running on 3 cylinders obviously, #4 is not doing anything.
I dont know what to do.
Here's what I checked!
INJECTOR issue? three different injectors have visited this cylinder with good o-rings. the problem remains. I remove the fuel rail and turned key to 'on'. there are no leaks.
Compression? Nope, all cyl reads 150.
Spark? I swapped plugs in 3 and 4 with no impact. I put the timing light on cable4 and it registers 22 degrees on the timing marks. Often there are missing flashes only on this cylinder. This is suspicious! I removed distributor cap and dont see any issues with making contact.
Thanks!!
