mine did the exact same thing......number 8 injector was stuck open.....changed it and it was fineWhidbeyStang said:I am pretty sure I have a stuck injector on mine. I am gettting fire to plugs but no FIRE. My plug was like a dry black or dark brown. Does not smell like gas. Looks like the plug has been dry firing. I did Cylinder Balance test and came up with no 4 cyl problem. It does feel like a dead cylinder. Idles ok, revs with no load ok, but drive it and you know right away it is not right.
Just messaged u about this problem.Wierd, I've got the exact same problem right now, and my #4 spark plug is the only black one out of all of them. It revs and runs fine, but once you load it up above 4k it misfires. No codes. Looks like i'm going to try to replace that injector.
If im having the same problem and hoping someone might chim in on the problem then why not? Kill two birds with one stone.... Plus isnt that why we use the search function instead of making a new thread.Next time don't revive a really old thread just to tell someone you sent them a PM.
