bad o2 sensor = bad idle?

I asked the man in the counter if it will do any harm if I drive the way it is now, he said no but I will just get poor performance. But, I don't feel any drastic changes in performance? Today, I changed the fuel cap and PCV valve and it seems to drive smoother. Maybe it's on my head. I might change the EGR valve tomorrow if the weather is better than today. Freakin freezing here today in Philly! I don't know if the light will go off??? Well, if after changing the EGR valve and the light still on..., now what??? I have to travel to Rhode Island this week-end and spend my Spring-Break with my family.

HAPPY SPRING-BREAK TO ALL OF YOU!!! :right:

you have to reset the ecu to turn the MIL off. if im correct on the P10s, turn the ecu screw all the way clockwise, wait a couple seconds, then turn all the way counter-clockwise. then its reset.

Oh man.....don't remind me. I HATE spring break because since I'm in the warmest part of Utah all the damn high-schoolers from the WHOLE STATE come and cruise up and down the whole town, but mostly the street I work on. C'mon people, what is so FUN about screaming out a car window and then puking? Don't get me wrong, I don't hate high-schoolers as a whole and I do know that a bunch of you are high-schoolers, it's just that when you take a town with population of 100,000 and throw in a bunch of obnoxious brats (about 20,000 of them) and NONE of them know how to drive....It's a living HELL I tell you.

Before you go splashing out on a new EGR valve there are some other things you should check first.

If you go here: http://www.se-r.net/engine/troublesh...de/tuneup.html and read up you'll find lots if info about the EGR system and links to repair procedures. It is possible that you just have some blocked tubes or dirty valves etc. that need cleaning out, and don't need a new valve at all.

Don't be so sure that you won't need to replace the EGR, the BPT valve, all of the connecting hoses and then finally the solenoid valve. All of these parts I recently replaced attempting to resolved the mysterious check engine light. Before I replaced these parts I went to a NISSAN dealer to diagnose the problem, The response was "It's something related to the EGR system"?. The scary part was that they suggest that I leave my car and they could not estimate a cost. I paid $60.00 to hear this.

And did it solve your Engine check light?? It's interesting to see how a component has failed - even if it ends up having to be replaced.
