Mass Flow sensor was relaced and the check engine light was reset but came on after approximately 60 miles.   After this a high pressure smoke test showed smoke coming out the #1 cylinder.  I was told it was the spark pulg seal and this problem could cause the check engine light to come on.  The idea is that if smoke is coming out, when the motor is running air was being drawn in changing the air fuel mixture.  

Another mechais said that this didn't matter.
