I just bought this car today and got a good deal on it so I got it with some problems. I have owned a few of these in the past one that I put nearly 300,000 miles on it. This one has 142,000 miles. And it runs great but has a ruff idle and a little hesitation on take off. It has brand new plugs and plug wires. No water in the oil or oil in the water. It does not have any over heating problems. The check engine light is staying on and the man I got it from said he thought the new plugs and wires would take care of it but it didnt so he gave up. I noticed the coil pack has junk yard neon marker stuff wrote on it. Not sure where to start. Fuel injectors? New coil pack? Maybe someone on here has had this same problem. Please help if you have.
