It finally came to me...
I had my 99 tour SE CEL turn on yesterday.
And, I took the car to the Ford dealer and have them check it out for me.
And they took me that was the "catalytic converter operating below efficiency" problem.
Oh...Ok I hear it, then the Ford guy said putting a "new program" in the computer should take care of it.
Hmmmm...I buy that, since I think the dealer would be better for the computer problem. It cost me $15X.
And then my shifter's buttom was a little bit had to pressed when I try to shift gear, I told the Ford to take a look at it. They said that was the shifter has a bad assembly(?) and if I want to replace it, that would be $36X. I figured that it might be cheaper if I take it to the other shop, so I decided to leave it.
Did I made the right decision? What do you guys thinks?
