I know its an easy DIY, but I'm currently not in that situation as my car was towed to a shop and didnt know that it was just coil ignition problem.
I'm getting 1 coil ignition changed out and all 4 spark plugs. The shop is charging me $85 (1hour) for the spark plugs, and (2hr) $170 for the coil ignition, I called up complaining about this because at first I was just given a total quote and figured the parts were expensive. On the phone the mechanic said its 2 hours because of important post diagnostics after replacing the coil ignition that they have to do. What's a true fair price that a typical shop would charge for labor for this?
