Rough Idle

Maintenance/Repairs

I have a 2000 Infinity Q45 with 99000k. When stopped at a light it sometimes idles like it wants to stall. This did not start happening until after the dealer did the 60000k major service. I have had them check this numerous times and they say the computer does not give them an error message. They have checked the fuel injectors and say they all appear to be working properly. I have tried fuel injector cleaner and fuel line cleaner. When it has the fuel line cleaner in the tank it doesn’t do it. Their latest suggestion is to replace all eight fuel injectors for a hefty sum of money and it “may” fix the problem. Do anyone have any other suggestions?
