Checking the mechanical bits is not a problem, the bits that can effect emission is a tad more difficult, so where do I start. I know that I can change the air filter but what else can be done, for example, is there anyway that I can check the MAF without having to use diagnostic equipment, is there any way that a MAF can be cleaned. What about the injectors, is there anyway these can be checked, You input would be appreciated.
