Hey all,
i just joined hoping to get some help with a 93 corolla DX with the 4afe engine. Car is running super rich and getting poor mpg's, so i did a basic tune, seafoam, oil change, plugs, cap and rotor and air filter...but its still super rich.
The car also idle very rough seems to be missing but all 4 spark plugs have good spark. Car also will just stall out when driving around 25-35mph
I tried pulling codes but the check engine light and O/D light just flash simultaneously.

Any help would be great.

no cel? Usually running rich would relate to o2 sensor but if it's not working, it also throws a code causing the cel.

ya no cel, i figured out the rough idle just about 10 minutes ago its the IAC acting up, now it just needs to stop snowing so i can feel my fingers and clean it out, and i'm gonna clean out the egr and the rest of the upper intake too.
I'll test the O2 sensor tomorrow and see if that has gone bad
