Hello Everyone,

Before this CEL deal, it was showing a code where it was too rich, and my cat was shot.
So I replaced my plugs, o2 sensor, my catalytic, and set timing back to stock and lastly reset the ECU. Took it to the smog shop here in CA, and it passed. Everything is running smooth. NO MORE CELs, in which I thought...

So here's the deal every once in awhile my CEL would turn on again while driving at speeds of less than 30MPH. It still shows the same exact codes from before. What else is there to do to fix it. Need your help folks.

Thanks!

Oh yah, I'm running your basic SUPER POWER mods(haha)! I/H/E.
