I put new plugs, wires, cap, rotor, module, pick up, fuel pump, fuel filter, oil and filter. This car runs good when it wants to, For gods sake it has a rebuilt 231 with 50,000 on it. I can't figure out why this piece of sh*@ has to bother me for something I can't put my finger on! I work as a part time mechanic and this is one car I can't figure out. I just wish I could find out the problem so I can help other people with the same problem. I won't get mad cause it leads to broken auto glass and dents in the rear quarter. this car is in great shape I just wish it ran as well. Once I figure out the deal I will let the world know!!! Black smoke, low rough idle, hesitation, and some problem starting. Help me and I'll help you.
