My Tahoe has been having issues for 2 years not being able to pass the emissions test. I took it to 3 other mechanics and a muffler shop here in town and spent a lot of money with no real results. I had a friend tell me to take it to The Car People on NW Broad and glad I did. Delontay and his guys not only found the problem in one day but had it fixed and me thru emissions the next day. In a matter of 36 hours they did what others had been trying to figure out for 2 years. I'd recommend them to any one having issues with there vehicles.
