So recently I removed my supercharger, plenums and intercooler tubes just for the fun of it, that and to make sure my valve covers weren't leaking. What can I say, my girlfriend was out of town and I was BORED! But it turned out not to be so much fun... anyway, when I was putting it all back together, I didn't put a new EGR gasket in place; I just reused the old gasket. I know... DUMB! But I was in a hurry (my girlfriend was due to be back in town)... not to mention I'm a moron. So now I have an exhaust leak type of sound coming from the top of my motor, especially when underway. Of course the EGR gasket is the culprit for the noise. But since I put my car back together, I also noticed the idle was screwy. When I start the car, it will rev up to 1500 for a few seconds, then go down to about 1000, where I presume it is supposed to be. After a few minutes of rough-but-not-too-rough (in fact, hardly-noticable-rough) idling, the motor will "bog" down and try to die.. after a second or two of sputtering, it will rev back to normal idle, but this time it idles noticable rough. Sometimes, though, it doesn't rev back up but just "lopes" and sounds crappy... My check engine light comes on, then goes off intermittently. It did this prior to the project though. So anyway, I was wondering if this crappy idling business might be due to the EGR leak. Probably not, but just wondering!
If the EGR is not responsible, does anyone know what else it might be!??! Thanks a ton...
