15 veiws and nothing to say well drove it last night ran fine drove to work and back ran fine( work is 3 miles away)

 

reset ur ecu. .the bad dizzy coulda had an effect on ur combustion which effected ur fuel trim.

 

Sorry to thread jack, but if a dizzy affected the fuel trim like u said, and let the car run real rich, would the tone of vtec cracking change compared to if the plugs were running brownish/normal???
