Okay so without realizing I had a terrible oil leak I made a 90 mile trip just to have it break down. It originally wouldnt allow me to accelerate it and then died. It wouldnt stay cranked. Had it towed to my house put 4 qtz of oil and 1 qtz of lucas treatment. It cranked but wouldnt even idle. I replaced the spark plug wires and the air intake hose because it had a huge gash in it. Cranks and kinda idles but if you try and give it gas at all it dies after you take your foot off the accelerator. I'm thinking I may have a vacuum leak somewhere but I have no idea how I would test it or where to even start. Theres a laundry list of things I've already replaced on this vehicle. It also buys think white smoke constantly and has for quite some time. Any ideas? Please help!
