My 2002 Suzuki Esteem was misfiring on 3 of the 4 cylinders. I replaced the spark plugs but it still shows it is misfiring. It doesn't have regular wires for the spark plugs. I don't have the money to replace everything. I need to know if I need new wires and possible ignition coil. The car seems to start ok and drive fine sometimes and other times it struggles to accelerate especially going up a hill. Please help.
