seafoam??
ok so here is the thing, i have been getting crappy gas mileage and someone recommended seafoam. so i researched it a little bit and it seems to be cool, but there is one thing that seems a bit sketchy to me. after you use the product it trips the check engine light, "engine misfire" or w/e it reads. Could this product be harmful to my engine? has anyone used this product on there vehicle? if so were there any problems afterwords? any info would be great....thanks...
