Hello, this is my first post.
My 2002 has a little over 118,000 miles. I started getting a rough idle a few days ago. I decided to purchase a new ETB. After installation and a frustrating relearn process it seems to be worse. My OBD showed code 0223 faulty TPS? I sent it back & put the old one back on. At that time I noticed some coolant in the intake manifold. Could it be a crack or a faulty gasket? Car still has a very rough idle.

Any comments are much appreciated.
