What is your question?
I put the negative battery cable on the battery, going to the car started up it runs for about five seconds then it starts to run a radically where I have to put my foot on the throttle to keep it running also the check engine light flashes but not a normal flash, it dims and gets bright, almost seems like a definite electronic issue.
What makes this problem better or worse?
Nothing
