The latest... I have had the TB off four times, bought (2) TB o-rings and (2) rear O2 sensors. I bought hose clamps and clamped every thing I could on the funky TB hose assembly. Tripped the service engine light and drove it 35 miles and the light came on again. When I started having problems with this was after I replaced the air filter and the car sit through the winter and I started driving it this spring the light came on for the first time. I decided to change the air filter and bought a different brand Nappa. I tripped the light and drove the car 60 miles and the light came on again. I was going to take it to have someone look at it. First I decided to drive it to our family reunion which is 600 miles, light was on. I came home and it sat overnight. I took it out for a short drive the next day and the light was no longer on. I have driven it a couple of hundred miles and the check engine light is still off.
