To bring this thread back to life...I've done the grounds refreshing again and no more unburnt fuel but now I'm getting a loud popping noise....sounds like a muffled back fire....
First time at a light at idle I thought it was someone popping a paper bag but I heard it on the hwy decelerating today and it's the same noise that I heard the other day....
Also noticed lately my water temp haven't been getting up to temperature lately it's been at about 140-150 degree range...I live in miami so cool weather is at about 75-80 degrees/windy
Could it be that the water temp. Not getting up to spec that it's dumping more fuel and causing the backfire? Or the o2 sensor may be going out as well?
