Pictures are tinted cause I hate the color of this car, but its the only 03 Cobra my dealership had. Now that Ive got more people looking at this post for a change, I need small help on a few minor problems. Ive concluded that the battery icon and hard starting as well as light dimming are a result of a bad alternator...that Im taking care of. But I have idling issues that are now going beyond a wobbly idle. When I start it and drive and then cost to a stop the car almost always stalls now cause the idle just drops too low unless a catch it in time and give it a rev. The rest of the time the idle sticks at 1200 on a dead stop before dropping...almost like the computer has forgotten where the car is supposed to idle. Im thinking this is a problem with either the IAC, the air filter or something else related to the air assembly. Its got 56K Miles on it and sorry to say it still has the stock air filter...Am I right about this? What can I spray to clean these parts and where do i spray it? Thanks
