Hey!! Some one hijacked my post!
My dad and I agreed in something. He should not argue me, or he will lose.
He took the car to a mechanic who has a very decent code scanner. He initially thought could be the coils (eventhough I told my dad why they wern't bad), but the scanner found a misfireing cyl #6. He moved the cable away from the o2 sensor and the problem was temporarily fixed. He erased the code from the computer and charged my dad only $10.
Dad told me the car was running good again and he was going to buy the cables latter today. And I told him I was going to thank you guys for the help and for being so precise, eventhough we ignored my recomendations
I will take it for a test drive on the weekend to see if she got back her "mojo"
