I am a new member to this forum, but i have a problem that i need help with. I am a fairly knowledgeable shade tree mechanic but by no means am i a pro. when i got this car it had been sitting for over 6 months and had a dead corroded and nasty battery and cables. i didnt want to spend a lot to get it on the road so i cleaned the terminals put a new battery in and changed the oil. the battery terminal recently broke so i cut the cable to change the terminals. the positive was corroded almost 6 inches under the insulation. so i changed the cables that went to the alternator and engine ground. now the car wont stay lit. she will crank and then sputter out. i can keep her going with the gas pedal but she is slow to respond and then races. i dont think i did anything...... please help me with my baby
