First issue is that i live in California and i can't pass smog because my check engine light does not come on at start. However i have triggered on purpose a problem and it comes on while I'm driving the car. I bought the car a couple of months ago with a bad tranny and recently replaced it with used but good clutch, new t/o bearing, andi kept original pivot ball. Whole doing this I noticed that thelowest car was converted to manual so I'm wondering if this has anything to do with check engine light? Someonewho please help
