Yeah I need to do fuel filter and all that bs too. Especially since the car is sitting all apart anyways. Contemplating ditching the AC too. Tearing everything out. Also ditching the power steering. But I can't get a manual rack yet, wonder how much they are used

i think sea foaming the car made your gas millage worse, fouled your plugs, gummed up your injectors and possibly dried up in flakes sitting on the back of every intake valve, using sea foam was a bad idea
