yea i sprayed some wd40 on the sensor tonight....going to let it sit.......spray some more and give it a go.....the battery light comes on when i pull to a stop then after a few seconds it goes away or is there but so lightly its hard 2 tell..........alternator looks new but has trouble with it, battery looks old, what could it be? plus when i push the brake excessively the idle drops bout a 100 rpm, normal?
went and got it smogged, vacuum leaks, new o2 sensor, and timing adjustment and it took the test like a champOriginally Posted by dill21831
well i decided to go to the junk yard and get another header w/o the O2 attached and get the new one attached to it and put the header on. I also put a new cat on too before going to get it tested. The part that sucks is, after doing all that and failing again, the guy says it may be a possible EGR valve malfunction. But I think he is wrong, cause it works perfectly fine, the only thing that I think that prevented the EGR valve from working was a loose hose that wasn't plugged in. So if anything I don't think I needed all that other stuff LOL. Oh well at least I know it will work for another 5+ years with the new parts on it. Still need to go and get it retested to see if I pass now that I know that the hose wasn't attached.
*EDIT*
Oh also, now my car runs a whole lot stronger and plus I have been kickin major butt racing, guess that hose was the main performance problem LOL, or not. But it maes me feel like it has gotten a whole lot faster.
i'm no mechanic and i need some suggestions... i just bought a 3g lx and previous owner failed smog twice. first time they said change cat, but he did this and came back and the car failed once again, but with worser results (almost twice as bad). i don't wan't to smog car again w/ trying to attempt to fix the problems. please help me....
There was just a thread in the Technical section about emissions. It ended up being the O2 sensor. You can test the O2 sensor if you have a volt meter. Disconnect the plug and with the engine running at 5K the voltage should be above 0.6 volts. When throttle is released the voltage should drop to below 0.4 volts.
Do a search and you will find alot more suggestions on failed emissions.
