96 esteem odb code 400
I have a 96 Suzuki Esteem 1.6L automatic. I got a check engine light the other day although it seems to be running fine. I recently replaced the catalytic converter maybe 6 months ago and now this. I cleaned the egr valve but it wasn't plugged or dirty. Anyone have any other advice? I ran the engine with the egr vac line off and it has vacuum, not a lot but it has vacuum.
