My name is Sybil Woodlief my husband Mack and I stopped in with car problems on that Sunday afternoon. We had the code read at auto zone next door. We had a coil pack replaced fuel injector treatment and a tuneup. The car didn't run any better by Tuesday the 28th so went to my mechanic at 1010 auto apex. I had fuel injectors replaced and he informed me that Mr Tire put the wrong spark plugs in my car he replaced them. I called and asked Mr tire said no discounted refund would be given. I am very unhappy about this I can be contacted at [protected]
