Hello I have an 03 blazer 4wd 4.3 v6 ls model and I recently changed a faulty injector on cylinder 3. (Did a scan and it said injector circuit malfunction, and cylinder 3 misfire so I assumed it was the #3 injector). That code is now gone now I am getting a cylinder 2 misfire I just put new plugs in wires look fine nothing bad inside the wire boots they have about 4k on them and the dis cap is good and dry, contacts look fresh on dis cap as well, new rotor also. So my issue is I have white smoke coming out of my exhaust at idle and acceleration the car is also overheating when I accelerate but not at idle and I took out my #2 plug and the electrode was bent. I think I know what it might be just would like some input please.
Thanks in advance

lower intake gasket possibly bad... as far as the bad electrode goes hard to say could have been done when installing could have got bent on taking out, worst case scenario piston hit it.. God for bid if that happened. just my thoughts..

 

When you say bad do you mean old because I just put a brand new fel pro on it and should also mention that when I took my oil dipstick out to check it my oil resembled chocolate milk

 

It does happen, or a bolt(s) might have loosened up.it does happen too.
