[QUOTE="cobrajeff96, post: 1504210, member: 29141"] Go to all factory ignition components, because almost every aftermarket coil/wire is garbage. You fixed the spark plug, might as well replace all plugs and all coils or coil packs, whichever you have. Because they could all have a hundred thousand miles on them for all you know. Hopefully that will fix any misfiring, but if it was running like crap for a long time then chance the O2 sensors could be heavy with soot or oil residue etc. Might as well replace them too as they're not super expensive and they're easy to replace. I'd do that after replacing the ignition components though because you may not have to replace the O2 sensors if the problem is fixed beforehand. Fix the coolant reservoir, don't want her overheating. Make sure to burp the air out of the system after filling it back up. Clean the MAF sensor with either MAF cleaner. And be extremely gentle.
