I have the greenbook and the car was with a set of issues before this one: black smoke, poor idle, soot, no start, etc. the car had a bad fpr (changed), a wrong ect (replaced by the OEM), bad O2 sensor (changed) , and bad pre pump (fixed). Everything seemed and work fine since these replacements, but it last only three months.... That is why I'm here again. If all that stuff was replaced by new ones, what it can be happening to get again the CEL on and 123 Code with no evidently signs of malfunctioning?
