I recently just added some injector cleaner (seafoam) in my tank and ever since doing this my car idle's very rough, and sometimes doesn't idle at all. I tried to rev it maybe believing some gunk built up as I only drive it 1 day a week or so. Now it won't idle and sometimes when I try to rev it starts to spit and backfire...and help would be appreciated. Fuel filter clogged???
