1990 Ford Taurus Pinging and other problems

Hi,

I have a 1990 3.0 v6 taurus. I had the cigarette lighter short my car out about a year ago. I drove the car when the short was bad. It would kill the battery every night. I changed the voltage regulator twice before I figured out tht the short was the lighter.

The car has run bad ever since. I did a full tune up a week later and it didn't help. I get a few pops from the engine when its cold and I accelerate. Doesn't do it when its warm tho. It will ping going up hills when it is cold or warm, it got better after running some fuel cleaner in it. When I put the car in park it will run for a few seconds and then die. It will sometimes die at a stoplight as well. The check engine light has never come on.

It ran perfect before this short. I passed emesions with some of the lowest scores tht I have seen. It passed emissions after the short tho but it took 2 times going thu and the scores were really high.

I'm wondering if there is something tht I can replace or if the short hurt a bunch of things?

Please help.
Thx Tom
