I have a 99 Honda Accord. It has a miss/rough idle when its parked for more than 4hrs maybe, but specially in the mornings. It's only at the first start, after that it runs normal. I have changed spark plugs, wires, fuel filter, fuel pump, and nothing has change. I took the car to scan it and it shows no sensor is bad, the person said that according to his experience it can be something in the fuel system because scanner is not reading any problem. Only thing I need to do is clean the injectors. Mechanic told me to put in the tank a bottle of fuel injector cleaner but I am wondering if its better to let a professional clean it. Or if there is anything else that can be the problem other than the fuel injectors. Please need help as I have spent a lot of money already and I am very frustrated at this point. Thank you in advance
