Hello,

First of all, I was wondering if you guys know what I need to do to check for the code 55 problem. I checked the vacuum lines to the EGR and they seem to be unplugged.

Second, what effect if any plugging/removing the EGR has on the engine? I searched the forum (took me a few tries since EGR is a 3 letter word, hint for others search for "emission removal" and its derivatives ie emissions, remove, removing) and all I can find is that no effect to remove the EGR on a carbed EA82, but what about spfi?

Third, if it has positive effects, what's a good way to plug the EGR and where to route the vacuum lines?

Thanks a bunch,

Andre S
