Honest business and technically very strong. I have a 2001 Toyota Corolla with P0171 code along with other codes. The car was initially taken to P**Boy, and they changed many parts. Some parts are completely unrelated to the P0171 code, e.g. power steering rack and pinion, oil pan replacement (no oil dripping), etc. Costed $2800 and the code was still there. Check engine light was still on. Then I took the car to Top Notch. The people at Top Notch are super friendly. They found the problem and fixed for very reasonable amount of money. Extremely happy with them. A+++++.
