RE-Advice

Thanks alot I will try that. If it turns out the coil is bad do you know any kind of a price for it? Also I do not think I am losing any coolant. Ever since I have had this car I have never even had a problem with it even going half way up on the T-stat.If I may ask one more thing. Was wondering if Ihad my upper o2 changed and the test still said I have a problem with my c-converter could it be that I need to change the lower one also?

i replace all three of my coil packs last summer, each coil ran about $23.00. they were pretty easy to do.

Well, if the downsteam sensor was sending a faulty reading, it might interpret it as a cat functioning incorrectly. It compares the two readings to monitor the cat funtion.
