For the past month, when started in the morning, my 86 LX-i idles at 2K and smokes through the tailpipe. After driving about 10 minutes, the engine light comes on and shows code 12. When she is warmed up, she does not smoke.
I changed the PCV valve (which was super clogged and gooey). Today I tested the EGR valve by applying 6 in/HG of vacuum. She ran really rough and the vacuum held steady and then she died (so EGR valve is working?). I then started her back up and tried the test again, however this time she ran real rough, kept the vacuum steady, but she did not die. Does that mean that the EGR valve is dirty and needs cleaning?
Also, if I try to adjust the idle to 800 at neutral, the oil light flickers? What is the exact cause of that? My oil dipstick level is right on, yet that flickering bothers me.
