On my 1999 Olds Alero in the morning my car starts very rough. It usually takes 2-3 trys to start it. The first and second time it slams very hard. Then when it does start it runs fine. I have had the coil packs, spark plugs and coil housing replaced in the past few months but it still seems like it starts rough. I recently moved to Houston Texas from Buffalo NY and I have been told that it could be the fuel filter and or ignition system. What do you think?
