1990 Mazda B2200 Q&A
1990 Mazda B2200 Question: My truck didnot pass smog test for the second time.
The first smog test became bad,but most of the error were fixed.Today got the second smog test,everything passed,but FAIL-ECS: other emission related components. Then the technitian wrote at the bottom of the results: BLACK SMOKE FROM TAIL PIPE. And was told a good tune-up will help. What can I do to solve the problem when my truck got sparkplugs,air filter,spark plug,wires,rotor and rotor cap replaced about a month ago???? What else should I do to get rid of that black smoke ???? Thanks for helping. - juancarloslax
