How much labour should it cost me for : a diagnosis, replace EFI relay & ignition distributor, replace front brake pads and rotors (which he initially quoted me about $500 for them with labour), regrease front wheel bearings & replace hub seals, replace by-pass hose & coolant & bleed, unblock air conditioner drain. I was charged $640, and that to me works out approx 10 hrs of labour.... would it take that long? and is a ignition distributor and ignition coil the same thing? please help asap... i need to know if i have been ripped off! thanks
