Whats going on everyone! 93 bird 3.8l auto. Anyways ever since the car sat for a month because the a/c compressor locked up. Got a new one problem solved. Starter went out same day! problem solved. Fuel pump made Wierd noises, problem solved. Basicly after i fixed the a/c compressor it started idleing rough only when i come to a stop light or stop sign. If you give it gas or driving normally it is fine. Only when i stop.. I changed the plugs today.. Motorcraft awsf44c. I'll do the wires,cap, and rotor later. Any ideas on what could cause that? I checked all my vacuum lines and connections all seem fine, I hear no leaks. BTW the whole front end of the car sqeals and squeekes. Only when i go over bumps.... Worn out struts possibly? Also there is a clunking comming from the passenger side of the car in the front only when i hit bumps as well... Any ideas on that as well? I'm Just doing the regular keep up of the car and hopefully will fully fix the noisy front end and a/c later. Might do the front end soon depends. Building my other car right now so I'm throwing the most of the play money at the play car. Any help will be appreciated!! Thanks everyone

I changed the wires, cap, rotor. All motorcraft and still the idle every now and then gets a tad bit rough. Sometimes u can barely feel it and others u can feel it. I'm gonna clean the fuel system and change the fuel filter with pvc valve next.... If this doesnt help I will determine that the motor might have internal problems or possibly a stretched out timing chain...
