Hi Everyone, I got an issue that I trying to put my finger on. My car starts fine on cold starts, but runs with an idle that rumbles... not very smooth. When the car is hot, or if it sits out in the sun on a warm day, it's starts with some effort, and runs very rough. I have to hit the gas and rev it up to get it running smooth. After that, it accelerates fine. But again, on low idle (800 or so), it has that rumble idle. The hot start was an issue before I replaced the spark plugs, wires, distributor cap and rotar. I also replaced the fuel filter and fuel pump. The rumble idle isn't something I remember before replacing all this stuff. Someone recommended running fuel injector cleaner in the tank thinking it may be a fuel injector issue. Good idea or bad??? Vaccum hoses all appear to be intact and tight. Any thoughts?
