Early last month I had my 2005 1/2 ton pickup in for a lot of work I just could not do as a “hobbyist mechanic” (I like to work on my truck whenever I can). Those darn O2 sensors just sort of weld in place and despite hours of trying, could not remove myself. C & A is the perfect option! Unlike me, they know what they are doing, have a very friendly staff, work with the customer, and come through as promised! Passed emissions no problem, and the other worn out parts they put on are working great. My vehicle is out of warranty with the dealership, C & A is a really sweet solution! No problems, no complaints, no disappointments.
