Vacuum leak

Postby davemeradith » Tue Feb 24, 2009 8:26 pm

<p>Hey Guys, after changing my spark plugs my engine ran like crap, like it was running out of fuel. I tried changing fuel filter but no difference. Tried regapping plugs again no luck. Sometimes it would run good but most of the time like crap. I thought i heard a vac leak and then it was gone. I kept looking then i found this <a target="_blank" href="http://images.yuku.com/image/pjpeg/80736c7d4d6395094d20f1983fedbdabc498c779.JPG">http://images.yuku.com/image/pjpeg/80736c7d4d6395094d20f1983fedbdabc498c779.JPG</a>. The ? i have is , what is it , it is located right after the air filter. Thanks.</p> <p><a target="_blank" href="http://images.yuku.com/image/pjpeg/80736c7d4d6395094d20f1983fedbdabc498c779.JPG">Image</a></p>

I fixed the pic for you, but I am guessing that is the EVAP line but does anyone know for sure?

thats the line that goes to the evap perge solinoid from the throttle body. check the vacuum line diagram printed on your hood

**edit** i just noticed your driving a 04+ so i could be wrong but the diagram should still be printed on the bottom of the hood

Postby davemeradith » Sun Mar 15, 2009 9:04 am

ok fixed line and car still runs like crap. I went to do a scan on the car and could not even get it to run good enough to go into boost. I took it home and cleaned the maf sensor and now it stalls on me when I stop. It's surjing. I will clean it again but I have a ? on the cai. I took it apart to get the maf sensor off and when I went to put it back together I did not like the fitment of the filter so I done away with the hose and the pvc between the filter and maf sensor, it just seemed like the fitment could have allowed a lil leakage between the joints. It is sealed up much tighter this way but i have to make somthing to seal up the cai around the hose coming out of it which will be no problem, but I am wondering if taking out that section of hose will disrupt air flow or should the front of the maf sensor straighten out the air flow enough. Ok you can tell me to shut up now!

Did you try to put the old plugs back in to see if it runs better? You might have a bad spark plug in the mix. That line is for the PCV fresh air not too critical but I would make sure its connected.

Before i cleaned maf it ran alot better but still not right. When I first changed the plugs I put in the oem's . That is when it started running like crap, but the old ones were discarded before I could see what they were. I then was told here that I should go al 104 so i did first at .060 gap then .055 and back to .060. and double checked them in between , and now I am worried I will wear out the spark plug holes...lol

Naa they are cast you won't wear them out.. Disconnect the maf all together the car will run rough for about 20 seconds and then clear up. If it runs ok with out the maf and you have a bad maf.
