EXHAUST FUMES EXCESSIVE
Problem - Lots of exhausts fumes. Very excessive.
Possibility 1 - Test the exhaust on an Exhaust Gas Analyzer to see what the numbers really are and to insure the engine is running within the specified numbers. You should see numbers in the range of - 0.80% - 1.0% CO & 100 - 150 PPM HC at idle....and slightly less at 2500 RPMs. If the numbers are not in that range it means the engine has some type of an issue.
Possibility 2 - pull the plugs and find the cylinders with the problem.
Possibility 3 - Vacuum hose loose, leaking or completely off. You may have fixed or changed something and forgot to put one of the hoses back on.
