To summarize: I would recommend cleaning out the EGR port on the back of the upper intake manifold (also called the plenum). This is not an easy job and it maybe worthwhile to have the dealer do the work. Local dealers quoted me around 200 dollars to pull and clean out the EGR passageways.

Cheers.

 

just dont fix it like i did...i replaced almost everything pertaining to this code and still havent solved it so if you do let me know

 

Did you pull the plenum and clean the port and EGR tube?

 

of course along with removing the throttle body and using a coat hanger to clean out the passage

 

and you still have the code?

 

yup changed the soleniod, checked function of the egr valve and cleaned out the passages...still have that fun 0302 code......luckly it doesnt really affect driveability so it doesnt bother me so much anymore....i always throw the 0707 code cause of my gforce ecu anyway

 

does this code affect gas mileage? I also have this SOB problem. My local shop told me that the way to fix it is to start replacing from the cheapest part...but that doesnt sound like a bright idea to me.

 

i dont think it does...it just seems to help emissions

 

i also have this problem except my car runs like **** my idle is very vicious it shakes my car real bad i have almost no power on accerlation and i have a huge amount of hesitation.

 

im telling you if you wanna try some coil packs this weekend let me know...i have a bunch lying around and you live about 10 min away


this also depends on wether or not i get my car back since my pcv grommet fell into my engine and the new one takes 2 days to come in.....also i broke another wire in my harness and need to resplice and make it longer

 

i had a friend and i tried his coil packs that work great and that didnt help : ( Im dropping off my car to the guy who put my engine in. Ill let you know what he says. Unless you want to help me take the intake manifold off

 

Thats not related to 0302...I have that and my car runs perfectly.

 

Well I'll be damned. You're not gonna believe it but there is a link in the HOW TO that shows what to check and how to check it. Your lazy *** should be banned.

i think the only reason i havent been able to remove the code yet is because i have a short or a wire break in the harness pertaining to the soleniod. when hooked up to the consult it shows the soleniods never stays open for more than a split second like its being shorted out

 

Vacuum leak?

 

If anybody local can check it out for me i'd be willing to pay....

 

i brought mine to the guy who put my engine in today does your car idle terrible ? If so the egr valve seems to stuck open. He still has my old motor so hes using it from my old motor and putting it on the newer one
