I was recently given a 1990 Dodge Grand Caravan.
It has 209,002 miles on it. It has a 6 cyl. 3.3L Chrysler engine. When we took it to get an emissions test, it failed. The technician there suggested that it may be either the EGR valve or O2 sensor. I have heard that there is a way to test if the EGR valve needs to be replaced. I'm wondering if that is true, and if it is, how do I test it? Thanks so much for your help!
have the same problem?
