First thing to do is pull the code. Either find someone with a logger or do the 2G trick, which I can't remember. I believe it's somewhere in the "1000 already asked questions." Something like turn the key on and off 5 times...conceyted said:well i keep getting a check engine light now..... no signs whatsoever of drippage etc... what could it be?!?!
That's a load of bullshit, I have no cat and I'm fine on the highway, just not when I get on itconceyted said:well the mechanic told me since i have no cat... that i have no back pressure so my o2 sensor is not reading anythign qand its just throwing all the fuel into the air fuel mixture.... so he suggests a 3 inch cat... i told him thats bullshit becasue i know a few eclipses and other cars with no cats that get perfectly fine gas milage... my o2 sensor is bad IMO what do you all think?
What the rear O2 (post-cat) sensor checks for is simply a different signal than the pre-cat one, I just wrapped mine in tin foil and duct tape and wedged it above a heat shield, does the same thing as a fake signal.conceyted said:already checked those... if the problem persists after these 02 sensors whats this thing about a fake signal for 02 sensor?
