I read online that Aamco offers free diagnostic checks I took my truck to a location in Houston The service attendant told me it would cost $113 to diagnose my truck When I spoke to him over the phone he said it would be free I drove my truck there with several lights illuminating in my truck I had no choice but to leave it there because I didnt want to risk more damage to the engine I was told if Aamco repaired the vehicle the $113 will be applied towards the total cost of repair I never seen $113 charge listed on the internet column stating its free 346-285-**** is my phone number Michael Moore Thanks
