Erik
Hare
St. Paul
Minnesota
Erik has a “blinky” Check Engine light. When he’s accelerating onto a highway and takes his foot off the gas to shift from 4th to 5th, the Check Engine light will come for about two minutes. He’s wondering what’s happening and if it matters. The problem is likely his oxygen sensor sending an erroneous signal. If it is just the sensor he can afford to ignore it, but the only way to be sure is to hook the car up to a scanner.
