New member here. Just picked up a 99 Lightning with 91k miles for 11k because it had a few issues. I have replaced the ignition coils and spark plugs. I will be rebuilding the snout next week as well. I am thinking it might have a vacuum leak since it had a couple hoses plugged off. Also thinking it might be the fuel pump but I'm not sure. Just want to do what i can on my own before taking it to a shop, Im located in Tucson but don't know of any mechanics that are reliable and not a ripoff. I will upload a video if i can soon. Any help is appreciated . Thanks in advance.
