Evening to all! Need help troubleshooting my engine problems. It started about a month ago when I was driving my Land cruiser towards work up a hill that was barely steep and that was a 3-4 miles stretch. After coming to a stop at a light and accelerating, I notice in my rear view mirror a big plume of smoke! Wasn't overheating at all, temp gauge was at the same spot every time. Pulled over immediately, popped up the hood and check to see if I had anything else going on. Radiator looks fine, coolant still green, and oil still clean (not milky brown)! Mind you that was a month ago, ever since then it never did it again.
Now about a day ago it did it again and same thing no over heating or coolant in oil. Head gasket was done 2 years ago. Drove to work today it was fine. New symptom occurred right went I started it up to go home! It started sputter, stumble, misfiring, and wanted to shut down. Turn the car off and popped the hood to check and see if anything is wrong. I see nothing, pulled on wires, checked all vacuum lines, checked fluids, and all the usual. Found nothing! Barely got home driving it only 45 mph! I started by pulling out spark plugs. 1 and 2 looked fine. 3 had a slight white dust on it! Didn't get a chance to pull out 4, 5 and 6 as it was getting dark. My question is what can be the problem? Spark plugs, spark plug wires, distributor cap and rotor, fuel filter, and head gasket was changed 2 years prior. Please need assistance!
