what color is the smoke?

White and it smells like fuel
Customer: replied 1 year ago.
Number one plug excess amount of fuel. Replaced injector didn't help
Expert:  Dan replied 1 year ago.

White smoke is usally coolant, black smoke is fuel. You need to do a compression test, but a leak down test would be better,

Hello again Dan here,

I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you’re not pleased, or need more help.

Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help?

Thanks Dan
