Thread: bunch of questions, please help

the car has had plugs and wires put in it recently enough that those aren't an issue, seafoam might be worth a try, how much does it run? the car runs great, just gets crap for mileage. how do I relieve fuel pressure on the 3.1 to change the fuel filter, I already accidentally found it, so that's out of the way. I checked both side access panels and neither have a fuse panel in it. the locks are vital to get working again, she has two kids and an ex and family after her.
