The OEM upstream O2 Sensor is damn near 300 bucks no matter where you get it. You can do the "generic" but you will have to wire your plug off the old one onto it. I was told not to use them, by someone that was not selling me the part, just FYI. Good luck.

 

I got my Walker upstream direct fit o2 sensor for $62 bucks. Don't use the universal o2 sensors, those things are junk.

Also, Advance Auto is having a sale on OBD II scanners right now for 50% off. They are going for right around $100. These are the GOOD scanners that come with real time readout and even logging capabilites. I bought mine about 2 years ago, and it doesn't leave my car. They are great to have.

 

i got the code read and this is what it says:


exhaust gas recirculation (EGR) flow insufficient

detected


probable cause

1. blocked EGR passage

2. faulty EGR valve

3. map sensor faulty

4. electrical condition on EGR circuit


i know the EGR hose is in the back of the intake mani back i could not see anything back there, im really confused rite now what do you guys think?


thanks

 

i had the egr code pop up the other day but cleared it out and havnt had it come back on so it might have tripped for no reason like i think mine did..have it cleared and see if it comes back on, if not then you should be good to go

 

Check the vacuum hose from the egr, might have poped off. Common ploblem on EVOs...

 

This. Got that code a few weeks ago and my hose was off....VERY common problem with our cars.

 

qft

I had the Mitsubishi dealership here tell me it was my intake causing my rough idle.... it was the hose popped off..

 

went into autozone a few days ago and they don't scan error codes anymore (at least in socal)! wtf

 

same here in NC, they told me it is illegal for them to clear codes because people coming in to get them cleared then go in for inspection



seriously guy below me, "autozone ftw?"
your posts probably the worst i have seen in a while, and that goes for all 14 of your posts
