Emissions

I have a Cadillac Northstar that had an emissions failure for a sticker and ran poorly. I took it to one of the advertised "big box" shops that fix everything for less and after spending $800 and the problem still there, they told me to go to a certified emissions shop to "get a waiver" as it couldn't be fixed. I took it next to a big, major transmission shop that says they "fix check engine lights." After another $1500, they said to get a waiver-it couldn't be fixed. The state hotline said to try Happy Bear as they always have had a 5-Star rating with the state. I did and they fixed it first time and I got my sticker. The other places were just guessing instead of testing and I HAD TO PAY! THANKS HAPPY BEAR!!!!
