This is a picture of the EGR valve in my 2000 DX Protege.

Just had my car checked out but lately I'm noticing little oil leak spots from underneath the passenger side of the car on my Garage floor. The spots are the size of dime. I had my mechanic check it out about 2 weeks ago & he said there was some oil around the oil filter left over from a...

Welcome abroad. Good to have you. Enjoy your car & best of luck.

DONE !

Oh btw, No after market. It's Drop In.

Yea I bought the kit & cleaned mine. Pretty involved process. How often do you clean yours ?

Thanks. Great Answers & Info !

Well now I'm totally confused on what to do ! The detailed explanation seemed to make sense. But experience and that much mileage sways me to high octane. But I just got laid off from Circuit City after almost 5 yrs of loyal service, so I'll stick to the cheap stuff for now. :)

OK I see your point. I just thought by running a high test fuel would help clean out Carbon Deposits. Was having an EGR code. "Excessive ERG Flow" Code PO402Thanks. You make good common sense. I'm going back to my cheap gas. :)

jersry emt, you may have a point there in the Mileage Dept. I do seem to get worse Mileage with the Chevron High Test 93. I usually get about 450 miles per tank on Low Grade. This is looking more like 350. Why the hell is that ? I would not think it would make much sense. ?????

and once again you answer another question. Thanks. That is good to know. When I spray the Throttle hole leading to EGR, that is what I will do. I guess if it comes back it didn't work. Thanks again. btw, my CEL came on today as soon as I hit a big bump. It probably would have come on anyway, It...

Question: Do codes come back after you disconnect battery, even if you Fix the problem. I know the code will still be in History, But if you fix the problem, then diconnect battery to shut off "Check Engine Light". Will the same code come back anyway since it was not cleared from the computer ...

Yea, cause I'm thinking. What's a few extra bucks every couple of weeks, if it is better for my car. Does high Octane Gas help with the Carbon Buildup on Intake Throttle & EGR ? Thanks.

So I'm thinking my car is not a "Pathetic Car". Therefore the High Octane would not hurt if I used it all the time. Correct ? I have 2000 DX 1.6 Auto Trans Protege.

Is it because of the high alcohol content, that some cars don't respond well ? Could it cause Engine trouble ?

here's a pic of what I think it is.

Engine Light Came back on today after hitting the 60 MPH speed. EGR must be stuck open but I don't know where or how to look for where the problem is without having to take apart the entire EGR valve assembly.

The guy who I bought my car from had the K&N Air Filter. The one you clean with a special Solution & then coat with oil. It's suppose to last forever I hear. Well the dealership told me it was dirty. I don't have the solution or oil to clean it with. I'm wondering is this filter all it's cracked...
