My car stops completely on the road when taking my wife to the hospital (she is pregnant). I am a frequent Pepboys Consumer, so I have them tow it to "My" Pepboys.
They did a no crank diagnostic on it and decided to do a tune up and flush my system totaling more than 700 dollars (which we had to borrow from family). They didn't check the ignition coils and sure enough right after I drove off the lot the thing was misfiring. I brought it back and they did another diagnostic (89 dollars)and replaced one ignition coil and the plate bringing my total spent over 1k.
When i asked why they didn't just do that in the beginning they told me that they only did something to get the car to run, but I informed them specifically that when I brought the car in that I wanted the car RIGHT. Needless to say the car is misfiring more because they still only did part of the job.
