OK, so I spend allot of time today trying to figure out my high idle. First off I pulled the codes and just got a 35 (high idel). I then looked for vac leaks with throttle cleaner. I sprayed every vac line and it didn't do anything. I then pulled off the EGR and found that it didn't have a gasket on it. I sealed it with RTV and put it all together. Same 1600 RPM idle.
I still suspect the EGR so I sprayed the entire tube with the car running. If I spray the EGR tube where it connects to the intake/throttle body it will sputter a bit. So I suspect I have a bad seal or my tube is slightly cracked.
Just now though I reset the computer and took it for a drive. I am now showing codes 33 AND 35. . I am hoping that this is just because the EGr is slightly leaking. This whole thing has me confused because sometimes the car idles perfectly (mostly when its warmed up), but other times it will idle at like 2200 RPM.
So what should I do now? I am guessing I should take off the EGR tube and go from there? Is there anything else it could be? I checked all the vac lines I could without taking a bunch of stuff apart.
Any help would be very appreciated. I know this is kind of a FAQ, but just don't know what I should do next!
