New thread, I tried tagging this onto an old thread, but didn't get far.
1990, LX, 5.0, manual.
My check engine light will come one, then go off, and back and forth for about the first 10 miles when I'm driving. I noticed this new problem after changing plugs and wires. While changing those i found a broken vacuum line on the passenger side. The little grey one which comes out of the center of the vac block just behind all the air intake piping. I patched that vac line up with an over patch and sensor safe silicon.
No issues with how the car runs, pulls well, sounds fine, idles nice. But when I push on the engine, under load only, clutch in no lights, I get the check engine light come on, then off and on again when i gas it.
I think electrical issues, some kind of short in the dash panel. But I did pull codes today.
KOEO 85 13 1
KOER 4 11
Very rarely the yellow/red portion of the tach dash light will flicker also, not at the same time or interval as the CEL.
Thanks for the help guys.
