“My 2004 Gmc envoy has 90,000 miles and the headlights and tail lights keep flickering when I start it. And when driving down the road they flicker. The gauges on the dash for the charging system goes up and down. I have had it to a chevy dealer 4 times know, first time they told me the throttle body needed cleaned. They did it. Picked it up and then it was just as bad. Took it back and they ran test and said it has to do with a plug for the secondary air injection system. They replaced it. Still doing it. …”
