Fuel Injectors Clean or Replace?
My 96 Buick is now 14 years old but has only 135,000 kms on it. It doesn't idle as smooth as it did when new and my mileage had dropped off just a bit. The plugs and ignition wires were replaced at 100,000 kms as part of a major tune up I had done. My question is: When should the injectors be removed and cleaned or simply replaced. The car is still running really well except for a wee bit of rough idle and poorer mileage.
Appreciate your advise or recommendations. Thanks: Bucky2
