from what i looked at in the manual it says that it goes to to the neck that protrudes up to the egr valve from the engine, but there isnt a connector there.

hate to bring up an old thread but does having this egr plug unplugged cause any harm?

i know where its supposed to go but there is absolutelty no connector for it on the egr valve where it says it goes so ive just been running it unplugged.

i have been noticing a hick up with the engine when it warms up completely. it doesnt seem to the engine skipping or anything within the ignition system. it almost sounds like a bit of unburnt fuel is getting into the exhaust or something. i was thinking this could have an effect on that.
