02 - rattle between 2100 and 2600 rpm
At first I was convinced that this was a fuel injector problem but after reading some posts I am not sure if it is a heat shield that is loose. I have been putting in a fuel additive the last 4 tanks and have not noticed a change, the fuel filter was replaced 16,000 miles ago so I think it is fine. I have never cleaned the throttle body, any advice on cleaning the injectors and cleaning the throttle body? I am going to check all heat shields tonight and HOPEFULLY that will stop the rattle.
